Fedora Servers :: Upgrade Fedora Release Keeping Raid 1 And Lvm?
Nov 13, 2010
I hope this is the right section, it looks like though. I have a small nas ( via artigo a2000 ) with 2 sata hd 1tb each with raid 1 and lvm on top configured and working great.
sda1 and sdb1 ==> md0 raid1 for /boot
sda2 and sdb2 ==> md1 raid1 for swap
sda3 and sdb3 ==> md2 raid1 as physical volume then volume group and lvs on top ( / is a logial volume of these )
I wish to upgrade the current fedora 12 32bit installation I have on it doing a fresh install. But because I have a lot of data on md2 ( 600GB worth ) which I don't want to copy across somewhere else first, I need to know how ( i am pretty sure i can ) to mount md2 during the installation. This way I can use the data I already have on it.

Does anyone have any experiences to share regarding this? Our server is still running Hardy and, of course, the time is rapidly approaching where I need to upgrade to the latest LTS. Now, I'm sure a complete re-installation would obviously be preferred, but I noticed that there's a release upgrade feature for Ubuntu server. Is this reliable enough to use on our production server without wrecking everything? I really don't want to have to go through the process of configuring software RAID and all our other services again.
Obviously I'll take normal precautions such as making tons of backups and starting the process on a weekend so if the proverbial poo hits the fan I can work over the weekend and have everything up and rolling by monday. This server is not exposed to the outside world as a webserver or anything like that so it can afford to be down over the weekend (although not preferable since we have financial cron jobs and such running in the wee hours of the morning).

Im having a hard time trying to change my raid configuration. Here is my situation:
A have two HDs that I configured in instalation time to work as raid squid proxy-cache. they are both 40GB. 40+40=80GB. So, I want to change it to two of 160GB. 160+160=320GB.
I have:
sdc1=40GB
sdd1=40GB
im adding / want:
sda1=160GB
sdb1=160GB
I want to remove the two 40GB and use only the two 160GB for my proxy. The thing is that when I remove the two 40GB, the system crashes at startup telling me that the raid cant be done then file system check fales too. Im wondering if there is a file a have to edit to change to point it to /dev/sda1 intead of /dev/sdc1 for example, so my system would start up looking for sda1(160GB) and sdb1(160GB) intead of sdc1(40GB) and sdd1(40GB).

I upgraded from F10 to F12 using preupgrade. The upgrade itself completed with no errors, but I'm unable to boot afterward.
Symptoms:...Grub starts, the initramfs loads, and the system begins to boot. After a few seconds I get error messages for buffer i/o errors on blocks 0-3 on certain dm devices (usually dm0 and dm2, but I can't get a shell to figure out what those are). An error appears from device-mapper that it couldn't read an LVM snapshot's metadata. I get the message to press "I" for interactive startup. UDEV loads and the system tries to mount all filesystems. Errors appear stating that it couldn't mount various LVM partitions. Startup fails due to the mount failure, the system reboots, and the steps repeat.
Troubleshooting done:...I have tried to run preupgrade again (the entry is still in my grub.conf file). The upgrade environment boots, but it fails to find the LVM devices and gives me a question to name my machine just like for a fresh install. I also tried booting from the full install DVD, but I get the same effect. Suspecting that the XFS drivers weren't being included, I have run dracut to create a new initramfs, making sure the XFS module was included. I have loaded the preupgrade environment and stopped at the initial GUI splash screen to get to a shell prompt. From there I can successfully assemble the raid arrays, activate the volume group, and mount all volumes -- all my data is still intact (yay!). I've run lvdisplay to check the LVM volumes, and most (all?) appear to have different UUIDs than what was in /etc/fstab before the upgrade -- not sure if preupgrade or a new LVM package somehow changed the UUIDs. I have modified my root partition's /etc/fstab to try calling the LVM volumes by name instead of UUID, but the problem persists (I also make sure to update the initramfs as well). From the device-mapper and I/O errors above, I suspect that either RAID or LVM aren't starting up properly, especially since prior OS upgrades had problems recognizing RAID/LVM combinations (it happened so regularly that I wrote a script so I could do a mkinitrd with the proper options running under SystemRescueCD with each upgrade).
I have tried booting with combinations of the rootfstype, rdinfo, rdshell, and rdinitdebug parameters, but the error happens so early in the startup process that the messages quickly scroll by and I just end up rebooting.
System details:4 1-TB drives set up in two RAID 1 pairs. FAT32 /boot partition RAIDed on the first drive pair. Two LVM partitions -- one RAIDed on the second drive pair and one on the remainder of the first drive pair. Root and other filesystems are in LVM; most (including /) are formatted in XFS.
I've made some progress in diagnosing the issue. The failure is happening because the third RAID array (md2) isn't being assembled at startup. That array contains the second physical volume in the LVM volume group, so if it doesn't start then several mount points can't be found.
The RAID array is listed in my /etc/mdadm.conf file and identified by its UUID but the Fedora 12 installer won't detect it by default. Booting the DVD in rescue mode does allow the filesystems to be detected and mounted, but the RAID device is set to be /dev/md127 instead of /dev/md2.
The arrays are on an MSI P35 motherboard (Intel ICH9R SATA chipset) but I'm using LInux software RAID. The motherboard is configured for AHCI only. This all worked correctly in Fedora 10.

I have a custom server built with Intel motherboard and RADI 10. The RAID controller is on the motherboard. I'm about to install fedora 11 x86 64 bit on it. Should I be experiencing any issues with anything that any of you have come across? I did a checksum check on the iso files and those were good. Also, someone sent me this link..

However, I have a hardware RAID, not software RAID.

How can we know which Raid level is useful for the server E.g Mail, Web, Database server. Also things we can keep in mind before configuring RAID / LVM on live servers.

I've tried to install Fedora 11, both 32 and 64 on my main machine.It could not install as it stops on the first install window. I've already filed a bug but really haven't seen any feed back yet.The bug has something to do with Anaconda and the Raid array but I really can't tell.
I have an Intel Board (see signature). I am running intel raid software under W7 currently.It works fine. But, I'm wondering, when I attempt to install F!!, is my current raid set-up causing problems? Do I need to get rid of the intel raid software and use a Fedor/Linux raid program to manage the raid array??

I am using Fedora 14 64 bit with two 1T drives. There is a Raid 1 for the important information and I use a Raid 0 for cached files that can be generated on the fly. Yesterday my Raid 0 went into read only mode.
Here are a couple of tests:
What caused the Raid 0 drive from /dev/md1 to get removed? Is there a way to get it back to active sync?
I have tried:
But it can not open /dev/sda2: Device or resource busy.

I'm setting up my first Linux install and I was wondering if I would be able to boot Fedora from a CD while keeping every other file on my computer, or in other words if I would be able to put the /boot partition onto a cd. I've also read that Linux can be booted entirely from a logical partition. If that's true then can anyone help me in setting that up. Mostly my problem is I already have four primary partitions, one being a logical drive with plenty of free space in it, and I can't get rid of the primary partitions I already have.

I would like to mount a disc that was previously used in the Intel Software Matrix RAID array (fake-raid). If I try to mount it I get:
mount: /dev/sdd1 already mounted or tempb busy
I think my dmraid is refusing to mount it beause of some RAID "flag". I would like to get rid of it, but unfortunately I cant do that on my system (theres no such RAID):
[root@ox mnt]# dmraid -r /dev/sdd
ERROR: isw: Could not find disk /dev/sdd in the metadata
no raid disks and with names: "/dev/sdd"
There are several posts recommending to uninstall dmraid completely from the system. Isnt there smarter solution in removing such a flag?

I have had no problem installing Fedora OS on any of my Dell servers prior to this post. Anyway, I wouldn't call this a problem but recently, we bought another DELL server with Quad Core, 4GB, etc... AND this model has 2 swappable SAS Harddrives.
I wouldn't call myself an expert but then again I am not a newbie too. However, I have never setup any RAID before and now I am forced to setup RAID1 on this server. So, in a way, I am a newbie in setting up RAID
Would someone please point me in the right direction as I have no idea what I am supposed to do to setup the RAID. FYI, I will be installing Fedora 10 64bit on this server. I would appreciate if you can start from the very beginning, ie. partitioning, formatting the harddrives during OS installation, etc..

I was recently requested to try and convert a running system to RAID level 1. I did not succeed in this task. However, I am still interested in accomplishing this task in a test environment.What I did was create a RAID device with a device missing e.g.
mdadm --create /dev/md0 --level=1 --raid-devices=2 missing /dev/sdb2
Once the RAID was up and running I created the /etc/mdadm.conf file so that it would activate the RAID device on boot. Once the device was created I copied all the data from the running root filesystem to the /dev/md0 device. The only directory that I didn't copy was the /proc directory. When I rebooted the machine I had a kernel panic and the system couldn't find /dev/root. I would greatly appreciate it if someone could provide some information/tips regarding the problem.

I'm looking to set up a bit of a home server, and am wondering about storage. What I'd like is something like RAID 6, which has good redundancy built-in, but with this being a home server, I'd prefer to start a little smaller and leave room to build it up in future. I'd been looking at commercial products like the 'drobo', which seems fairly ideal, but I'd really like to see if I can do it myself. I understand that throwing the RAID into an LVM will allow for some expansion, but the last time I checked, most RAID setups called for the same sized disks, or at least limited the array by the size of the smallest disk present.
What I'd like is the ability to build a basic framework with a few cheap disks, and then as things start filling up, to be able to add larger ones (perhaps eventually pulling out smaller ones as though they'd failed and replacing them with big ones)

I really hope this is revelant here, and that someone can help. I have been using fedora for a while now, and I love it. However my brother has started using ubuntu, and wants me to at least try it, which I agreed to. I have created a partition for ubuntu, using Gparted, in fedora 13. My question is, how do i install ubuntu onto this existing partition, whilst keeping the Fedora boot loader, which I think is absolutely fantastic, and would love to keep. In summary; how to install ubuntu on an existing partition, and add it to the fedora boot loader options?

I have two Ubuntu 8.04 servers currently. I've purchased some 500 GB hard drives and a RAID cage just yesterday and plan to change my current servers to using RAID1 with the hard drives. Much like everyone else, I have the nVidia RAID built onto the motherboard that I plan to use. There are many how-to's out there on how to setup RAID using dmraid during the install process - but what would a person do if they are simply changing over to a RAId system? I installed dmraid a few days ago on the server. It seems that even though I have RAID shut off in the BIOS, it saw the one and only drive as a mirrored array. When I rebooted today, the server would not start; it had ERROR: degraded disks.. bla bla. Then Grub tried to start the partition based off the UUID of the drive (which was not changed) and it said "device or resource busy" and would not boot.
This problem was corrected by going into the BIOS and turning on RAID. When I rebooted, the nVidia RAID firmware started and said degraded. I went in there and deleted the so-called mirror keeping the data intact. Rebooted, disabled the RAID feature in the BIOS and then the server loaded normally with a message "NO RAID DISKS" - but at lest it did boot! So this leads me to believe that trying to turn on a RAID-1 array (just mirror between two disks) may be a challenge since I already have the system installed. I will be using Partimage to make an image of the current hard drive and then restore it to one of the new drives.
The next question is - is it a requirement that dmraid is even installed? While I understand that the nVidia RAID is fake-raid - if I go into the nVidia RAID controller and setup the mirroring between the two disks before I even restore the files to the new disk, will both drives be mirrored? However, I do think that I'd probably have to have dmraid installed to check the integrity of the array. So, I'm just a bit lost on this subject. I definitely do not want to start this server over from scratch - so curious to know if anyone has any guidance on simply making a mirrored array after the install procedure, what kind of Grub changes will be needed (because of the previous resource is busy message), and whether installing dmraid is even a requirement.

I have an old server I build 7 years ago. I have a RAID5 with 5x2TB HD's and I'm planning a major hardware overhaul. My server currently runs on a Pentium4 3.2 Ghz (pre multicore technology) on a SuperMicro mobo. I'm planning to switch to an AMD Phenom II X6 1100T Black Edition Thuban 3.3GHz, 3.7GHz Turbo 6.
So here's the question. Can I just plug my drives to the new board and restart the RAID like nothing happened? I don't have space to backup all my data if I have to recreate the RAID from scratch.

I had a RAID1 'device' build on two physical partitions on two drives. One of the disk controllers died and software RAID did the job - now I am working on the degraded array.
Now I want to put the old disk (sdb) back, and I am not sure what will happen. Both disks have 'raid auto' partitions. And sdb file structure from before of the failure. The raid code will find inconsistency between both partitions. What will it decide? Will it start coping from the currently running system (sda) all the data to the old one (sdb) at the boot time, as I wish?
I don't want to it to write from the old one to the new one, as some months passed and lots of changes happened to the data.

Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.

just as the title states i need to upgrade my os from fc4 to fc10 first let me say i have no physical access to the box. all i have is root ssh access to it. So i need to know the best way of upgrading that will be safe. before i do the upgrade the server will be backed up so i will not loose any files. if the upgrade fails the data center will reload the os with what i need on it. but i would rather not have to format.

Automatic upgrade ver 10 to 11 Have a large drive that is shared over Windows domain.This was renamed from /media/drive/ to /media/7534179143A7E34 All the users in Windows domain can not access the files or folders on the Fedora server - Samba setup. Why was the deive renamed and is this causing problems. I reshared the folders on the drive but still cannot access the drive. Where do I start to fault find please.

I have upgraded one of the computers on my network to Fedora 14 (previously Mandriva 2010.1). There's a directory on another machine that I want to mount on this one. The directory can be mounted OK on two other machines in the network (including one running Fedora 13) and, before the upgrade could be mounted on this one, so the nfs server is OK.
If I try to mount manually I get the following:
[root@lipwig Documents]# mount -v 192.168.8.4:/backup /mnt/librarian/
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Tue Feb 8 12:17:00 2011
mount.nfs: trying text-based options 'vers=4,addr=192.168.8.4,clientaddr=192.168.8.12'
mount.nfs: mount(2): Operation not permitted
mount.nfs: trying text-based options 'addr=192.168.8.4'
mount.nfs: prog 100003, trying vers=3, prot=6
[Code]...
/etc/hosts has the names and ip addresses of all the machines on the network so the reverse dns lookup (which I have fallen foul of in past years) shouldn't be an issue. So I'm kind of out of ideas. I don't recall there being any problem accessing this mount with Fedora 13 .

I have a HP ProLiant DL580 G2 running a freah install of Fedora 9. After doing all updates and re-booting the sys monitor only shows 3.7gb of memory with actual 8gb installed.
Not sure what is going on. Current kernel version is: 2.6.27.9-73 fc9 .i686
I was under the impression that F9 was a PAE kernel. But doesn't look like it to me?
Do I need to upgrade to Fedora 10? Or install a PAE kernel?
If a new kernel, what do I do? I'm new to Fedora 9 and big iron servers.

Been away for awhile (Fedora 5 or 6 was what I last ran). Just downloaded Fedora10 and installed it on a drive here, running great, looking slick. What drove me back to Fedora (Linux) is my need to create a simulated webserver to locally test stuff without messing up my live site. I had successfully installed php and mysql, using the specific versions my host uses. I then downloaded the RPM of the specific apache instal, followed the install directions and ran into a snag. Last step, says, "$ PREFIX/bin/apachectl start". I did that and received an error. Tried just typing apachectl start, and it worked. Upon my surprise it loaded Apache 2.2 (mine was a 1.3 release), and of course is Fedora-branded.
My questions are as follows:
Do I know somehow how two versions of Apache on? How do I start up the 1.3 one if so?
If not - How can I remove the 2.2, and what will have become of the 1.3 I installed?

I guess it should be possible but some tips / guide would be great so I don't kill my windows and have to reinstal all over again, as i wanna keep windows as main OS for work but have fedora to learn as well.By the way, I have 2x640Gb in raid0, 1st partition 100gb with Windows7 on it, and the rest on another partition. Both have data on them. If that means anything for instalation
