I need to replace a disk from a veritas mirrored volume, I can not delete the disk from the diskgroup as the disk is using by other volumes in the same group. so, how can i remove the disk from my mirrored volume and can replace another disk.
View 1 RepliesI want to practice Veritas Volume Manager on my CentOS 5.5 x86_64 machine.
Thus, I have downloaded the appropriate package i.e. Storage Foundation and HA Solutions 5.1 SP1 for Linux Red Hat from here.
I believe this is the 60 day trial version. Does anyone know if it has some limitations also in this 60 day period ? Forgive my ignorance, I am new to Veritas.
Fedora 11. I am trying to setup kickstart so it lays out a mirrored volume group. I have 2 disks sda and sdb. I want a primary partition on each disk 200mb in size for /boot. This is to be mirrored onto raid device md0 (raid 1). The rest of each disk is to be setup partition which grows to use the remaining space, and is also mirrored (raid 1) md1. Onto md1, I want an LVM volume group called rootvg, and logical volumes set up on there for /, /home, /usr, /tmp etc. I can lay this out manually, and it works fine. However, the code below, which is slightly amended from a previous anaconda-ks.cfg file doesn't work.
Code:
clearpart --linux --drives=sda,sdb --initlabel
part raid.11 --asprimary --size=200 --ondisk=sda
part raid.12 --grow --size=1 --ondisk=sda
part raid.21 --asprimary --size=200 --ondisk=sdb
part raid.22 --grow --size=1 --ondisk=sdb
raid /boot --fstype=ext3 --level=RAID1 --device=md0 raid.11 raid.21
raid pv.1 --level=1 --device=md1 raid.12 raid.22
volgroup rootvg --pesize=32768 pv.1
logvol / --fstype=ext4 --name=rootlv01 --vgname=rootvg --size=512
logvol /home --fstype=ext4 --name=rootlv02 --vgname=rootvg --size=256
logvol /tmp --fstype=ext4 --name=rootlv03 --vgname=rootvg --size=128
logvol /usr --fstype=ext4 --name=rootlv04 --vgname=rootvg --size=3072
logvol /var --fstype=ext4 --name=rootlv05 --vgname=rootvg --size=1024

is it possible to extend a mirrored veritas volume which has two SAN LUNs each one in a seperate EMC storage box.
i need to add diska -> EMC box1
and diskb -> EMC box 2
then i need to increase the size of the mirrored volume.
I've installed Debian Squeeze twice using CD1. First time with a high-speed internet connection using a mirror, 2nd time without. With a mirror, much more is installed, and clearly a much more complete installation. What packages would I install to make a basic CD install more like a mirrored install? Is there a list on the CD somewhere?
View 5 Replies View RelatedI have an internal hard drive split between Windows 7 and Fedora 12. The Fedora 12 install exists on a LVM which presents a bit of a challenge when trying to mirror the drive. I was trying to use gparted but it doesn't have support for LVM. I discovered g4l, which does a bit-by-bit copy and ran a full disk copy using that from the 500 GB internal to a 500 GB external. Inspecting it with gparted, the copy LOOKS like it went correctly.
However, when I disconnect the internal and attempt to boot to the external (specifically in the BIOS), it's unable to boot to it. It instructs me to insert bootable media and try again. Has something gone wrong with the copy? It SEEMS like g4l finished faster than it should have given the copy rate it was operating at (I had figured out when it should finish up), but the screen saver had been on and when I came back it was back at the menu, so I don't know if it got to 100% or ended prematurely? There were certainly no error messages...
I own an Iomega NAS enclosure. It is basically a card with 2 sata drives attached and a network card that runs an small web interface. To make a long story short. The controller card has went bad. One drive dropped out of the mirrored set.... and then came back in and attempted to rebuild. Several hours later the drive dropped out again. I attempted to replace the drive and the controller would not rebuild at all.
To summarize. I have accepted that the controller card is toast and want to proceed assuming one drive is compromised and the other still has salvageable data (About 18 GB needs recovered) I took the presumed "good" drive.. attached it to a standalone enclousre that takes it from sata to USB.When I look under disk manager (using Ubuntu 10) I see the following appear
1) the multi Disk device appears indicating it is part of a logical drive. Indented from that is
2) The "Array" Icon
3) The USB icon indicating a "peripheral device" Indented from that is
4) the Drive as a 500 GB hard disk (correct)
when i click on 4) I see 2 volumes 1 1GB volume with partition type Linux (0x83) and a 499 GB partition with the same type (0x83) However..because it thinks it is part of an array it is not mounting. HOW do I tell this drive "you are not in an mirrored array anymore...mount as a single drive"
There is a disk 500 gb, it is broken on /boot and on /root and on /dev/sda1 and /dev/sda2. Whether prompt it is possible to redistribute a disk without loss of data namely it is necessary to make/boot and two equivalent on disk volume.

View 1 Replies View RelatedI have a 2 node RH 5u4 64-bit. I have installed and configured the latest Veritas CFS (Cluster File System) which also uses Veritas Cluster Server. File system if VxFS. Storage is on EMC Symmetrix arrays with Veritas Mirroring between the arrays.We have noticed that running 'du -hs' on the shared directory/filesystem where it takes about 3 minutes on one node and 30 - 45 minutes on the other node.I've been running strace on 'du'.'du' runs an 'lstat' on each file (66,000+ files). On the slower node, the ave time spent in 'du' is about .001 seconds longer, which accounts for the 30-45 minutes. Also, the standard deviation is much larger, which means to me that the lstat times are all over the place!Another interesting thing is that iozone profiling shows that the i/o rates from both nodes are darn near identical, with no anomalies at various buffer & file sizes! And, iostat looks really good as does 'vxdmpadm iostat show
View 3 Replies View RelatedI am running a server in Dell which has RAID1 and hot plug 2 disks. It's been running for a while, but I was thinking it may crash anytime. So got a spare one, and wanted to test it how it works.I have never done this before. Can I simply, on a running machine, unplug the Disk 2 and connect the new Disk there? (Without interrupting the service as a silent mode?) Or does it have to be shutdown first, and unplugged, reinstalling all software/centos/etc etc? How do you do this update? Also how do you know when you replaced the disk? Do you have anything special to monitor that disk 1 or disk 2 is end of life?

When i try to mount the logical partition. The system hangs.
"mount /dev/fileserver/media /var/media"
I have tried locating the problem without success. The same with a live cd.
Here are some of the commands i have run:
http://pastebin.com/gYyJtUvQ
Kernel 2.6.21.5, Slackware 12.0
Code:
root@darkstar:~# blkid
/dev/sda: LABEL="MAESTRO!" UUID="4730-D359" TYPE="vfat"
/dev/hdc: LABEL="STORE1 ver. 2 (overrules ver. 1)" TYPE="iso9660"
[code]...
As you can see, the first command gives numbers like C841-0655. But for the optical disks (iso9660) it gives them not. Neither does the second one. This number is known as 'Volume serial number' in MS-DOS, and is printed on console with the command 'dir' not only for the HDD partitions but for the optical disks too. how to get an optical disk Volume serial number? Notice that this number is inherent to the media (is a property of the media, under any O.S.).
I have 2 hdd
lvm was created in 2nd partition type primary.
yesterday i had deleted all partitions in the first drive of windows only from ubuntu disk utility. today i went to install windows and the partition space was shown as [139gb] , i thought this is the first hard disk. But my guess is windows must have taken the free space on my home partition inside lvm[ 150gb which roughly translates to 139 GiB.
SO first i deleted the whole partition of 139gb which was shown different in unallocated space as a slight less figure and then i created a 30gb partition on that space shown and went ahead, windows post creation again showed 139gb and then gave a message on next window that partition does not contain data to install windows xp. Strange i thought, this becoz next screen before the format partition as ntfs is all to be shown. Then i just felt something fishy and rebooted and then ubuntu of 2nd hdd is not booting.
I ran test disk from gparted live cd and i find td recovered the boot drive but not the 2nd primary partition in which lvm [root,home,swap] is created. It shows the lvm as 279gb. But not the 3 logical partitions inside it.
Now when i boot post the grub menu i get the following message
This disk contains all my data and the first drive was also wiped out full. test disk is not able to get anything on that windows drive.........
I plan to install a server using LVM. I thought a partition schema where /boot would be in an ext4 partition while / /usr /var /home and /opt would be in the LVM. My question is: if I'm putting / into the LVM, is it necessary to divide /usr /var /home and /opt into different logical volumes? If I divide them, would it become harder to maintain when new disk space has to be added to the volume group?

I dont know if this is possible or not but here what I would like to do. I have 6 linux server and each has 100GB disk space. All of these 6 box are compute nodes and space are not used really. However, If I can combine 6 servershard disk that will in total 6*100GB gives you quite a bigger space. Is there any tool or ways to mount these drive in one volume instead of mounting individually ?

View 1 Replies View RelatedI ran yum update on my centos 5.6 box a couple of days ago and following this the system would not reboot, dont recall the exact error and don't seem to be able to find it logged anywhere but it was something to do with LVM not being able to find a disk.
In the end I have booted to linux rescue and edited my /etc/fstab file so the system does not try to mount the offending volume group. This enables the system to boot but I need to find out what is wrong with the system and get this volume group accessible again. Here is my edited fstab showing the commented out line. code...
I've added a new LUN to my Centos 5.2 server using Powerpath and have added it to an ext3 logical volume. I extended the logical volume using lvextend and the new space shows up correctly in lvdisplay. What I'm having problems with is getting Centos to see the new disk space (df -h shows 500GB, not 600GB as expected). I've tried running a resize2fs on the new volume but it tells me that "the filesystem is already n blocks long. Nothing to do". Does any one know where I'm going wrong? If possible I'd like to sort this without a reboot.

View 2 Replies View Relatedhow easy it would be to read the contents of a physical disk that was part of a larger logical volume. The disk contains a "Linux LVM" partition that spans its entire size. My problem is that one of my disks died, and I have to send it back for a warranty replacement. However, the disk is dead, and I can't zero it out. I'm just trying to assess how difficult it would be (or at least how likely it would be) for a tech that's checking out the disk to get at the data.

View 2 Replies View RelatedI had Windows 7 RC installed and F10 on the same machine. HP 6730s Intel Dual Core. Everything was working fine and I don't remember doing anything special when installing Fedora 10. I decided to install F11 from DVD, installation went fine but after rebooting all I get is "non-system disk error or disk error. replace and strike any key when ready". I couldn't find any relevant post in this forum and googling I found that this could be a disk starting to fail but I don't thing this is the case here. I'm trying to reinstall just now, I chose to install grub at /dev/sda (default), should it be /dev/sda1 ?

I often use dvdbackup to mirror dvd's to my harddrive. I used to use k3b to burn them to disks. The problem is I no longer use kde, and I realy hate installing kde apps these days, since they seem totaly bloated. Brassero isn't smart enough to take a directory with a dvd's file structure mirrored into it, and burn this as a video dvd. Is there a way to convert such a directory into an iso from the command line so brassero can handle it?
View 2 Replies View RelatedI was wondering what is the proper way to setup a hardware based mirrored raid. I have two 2TB drives and a nvidia based raid on the motherboard. I used the nvidia raid manager to setup a Mirrored array consisting of those two drives. The total shows as 1.81TB array.
I boot into OpenSuSe 11.3 and in the partitioner I see two drives (dev/sda and dev/sdb each 1.82TB) listed instead of a single RAID drive. Am I doing something incorrectly that two drives show up instead of the array? Does something need to be enabled?
I have mounted a mirrored array on my linux machine. I used the Nvidia raid controller in my bios and mounted the resulting raid drive.
under /dev
the 2 drives sdb (2tb) and sdc (2tb) are symbolic links to
/dev/mapper
nvidia_dcabdggcp1
I then created a file system on nvidia_dcabdggcp1 and mounted it to /share
the output of my df -h is
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
897G 8.0G 843G 1% /
/dev/sda1 99M 19M 75M 21% /boot
[Code]....
Is there a way to check to make sure that my mirror array is actually working correctly without unmounting/remounting the sdc drive somewhere to see if it's a mirror of sdb.
