CentOS 5 :: Persistent Overlay Not Working On Ext3 USB Drive For CentOS 5.4
Dec 3, 2009
i am trying to get centos 5.4 installed and bootable on my 16gb flash drive, with persistent overlay using and ext3 formatted drive.i want to be able to boot into centos and be able to have all updates from yum, etc, saved when shutting down for my situation i cannot use vfat.
I just tried Centos 5.2 Live starting from a 2 GB USB flash drive. Everything seems to run fine, fast, stable - except for that the persistent feature is not working. I created the USB from Windows using the Centos 5.2 LiveCD image and the current version of Live USB Creator (3.7), and declared a 256 MB persistent space.
This persistence feature had worked before with Fedora 11 but the system resulted unstable, kernel panic.... Now Centos has been solid for hours in a row... but the file where persistence should be reflected remains untouched with the initial creation timestamp. When rebooting, every change in config, file created etc gets lost.
I just set-up my fedora-14 live usb on an 8gb usb hard drive but I see the space left on '/' is less than 800mb (I created a 3.5gb persistent file) like so: Code: livecd-iso-to-disk --unencrypted-home --home-size-mb 3500 --overlay-size-mb 3500 Fedora-14-x84_64-Live-Desktop.iso /dev/sdc1 but I still don't have much space to install programs.
Is there a way to trick yum into installing programs under /home/liveuser/programs instead ?: Code: [liveuser@localhost ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/live-rw 3.0G 2.8G 223M 93% / tmpfs 1002M 352K 1002M 1% /dev/shm /dev/sdb1 7.4G 2.0G 5.1G 28% /mnt/live /dev/loop5 3.2G 130M 2.9G 5% /home varcacheyum 1002M 0 1002M 0% /var/cache/yum /tmp 1002M 92K 1002M 1% /tmp vartmp 1002M 0 1002M 0% /var/tmp
I have a server wich is connected to an iSCSI storage and gets harddisks from this storage. Sometimes I have to add new disks to this server. Everytime I add a disk and make an /etc/init.d/iscsi restart on the server the disks don't have the same device name as before the iscsi restart.
It should be possible to gave the disks persistent names using udev rules. Now I tried to create different rules in "/etc/udev/rules.d/99-static-iscsi-names.rules" e.g.
# /dev/sdc KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -s %p",RESULT=="360a98000503355344c4a576864467877" NAME=="sdc%n" In "/etc/rc.local" I added "/sbin/start_udev" and in "/etc/scsi_id.config" I added the line "vendor="NETAPP",model="LUN",options=-g"
I have a 2TB hard-drive connecting via a usb port on my server for automatic backups. I noticed the backups had stopped working and then I realize I had lost the ability to communicate with the drive.
/sbin/lsusb gives: Bus 005 Device 001: ID 0000:0000 Bus 002 Device 003: ID 046b:ff10 American Megatrends, Inc. Bus 002 Device 001: ID 0000:0000 Bus 002 Device 002: ID 046b:ff01 American Megatrends, Inc. Bus 001 Device 005: ID 059f:1018 LaCie, Ltd
I've just installed CentOS 5.4 on my Thinkpad T43. Everything works fine except one thing that, when I suspend the machine, the hard disk is always shut off in a "hard way". The sound is similar to the one you would hear when shutting down the machine by keeping pressing on the power button.. this is no good.
I am trying to install Centos 5.6 on a motherboard with a built in Marvel 88SE61xx drive controller.NO drive arrays are configured using the Marvel BIOS configuration utility.During the install CENTOS displays loading MARVEL_PATA driver and it waits and waits and waits.Looking on one of the system message screens I get the following types of messages:qc timeoutfailed to identifyI/O errorLink is slow to respondSRST failed errno=16ata4: reset failed - giving upAny ideas as to how to get CENTOS to recognize the drives connected to the motherboard Marvell controller on a NON-RAID configuration?
I am having new hardware and IDE driver for that hardware as drive disk image (it8213_centos53.img). CentOS 5.3 installation is working fine with drive disk image at USB and CentOS 5.3 at DVD. Our application uses CentOS 5.3 and we build a custom kick-start ISO for installations. Using that ISO client is going to install on all hardware boxes.
Note while installing : a) No network connection is avalible. b) No USB isavalible. c) No floppy is avalible. d) Only single CD-ROM is avalible.
So, is it possible to build single custom kick-start CentOS 5.3 ISO which contains dirve disk image and entire installation will be done using that image. If so please let me know the steps to build it.
I am trying to clone the hard drive to a slightly smaller hard drive in the same computer, same setup.What software or commands do you use to clone the entire system and resize the partition automatically?The original HD is a little larger than the destination HD. The source partition only has about 20 GB in use and the rest is blank.
I have 2 partition, a small 100MB boot partition and another 500GB LVM partition.I can't just clone from the original disk to the new disk. (for another long reason) I need to make an image of the original disk on an external USB drive first, then move that image onto a new disk.I have tried creating an image of the whole disk with Clonezilla, but then the restoration didn't work because the target drive is smaller than the original.
I'm using CentOs 5.4 (2.6.18-164.15.1.el5 #1 SMP Wed Mar 17 11:30:06 EDT 2010 x86_64). I tested out ext4 on a partition for the last few months and it seems to work fine. The issue is that quotas dont seem to work correctly on it. Is there a way to revert back to ext3? Mainly the quota tools do not work on it.
I've installed a new fresh Centos 5.5 ..and after a lot of work..something starts to work (X now works with the new ATI HD5145 using ATI drivers) but i've a serious problemThe ethernet controller JMC250 JMicron PCI EXPR. doesent work at all so my notebook is out of the world !!!Here is some infos:rpm -q centos-release
I have a external usb 20Gb hdd. It was a ntfs partition but i could'nt mount it, so I try with a ext3 partition, because with centos it's mount automaticly, but... for some reason that I don't know, even with a ext3 partition my centos don't detect my external usb hdd, howerver I already try to mount it on ubuntu to see if it work, even on windows with some programm to recognize ext3, it was alright, but why can't i mount it on my centos?
I installed CentOS. NetworkManager successfully installed and launched. I can ping any IP from terminal but I can't open any site in browser except 127.0.0.1 I can't open IP of the modem 192.168.1.1 in browser also.
With the release of CentOS 5.5 ext4 is considered stable in this distribution so I decided to migrate to it. Luckily I started from migrating fresh server with CentOS 5.5 using some instruction I found on the internet. I think I shouldn�t say, that I screwed the whole thing up ;) After about 6 hours cursing, kicking, and crying I solved the task and figured the correct sequence of actions. The small problem with migrating root partition is that you can�t unmount it BTW.
During migration task, I found, that CentOS 5.5 rescue mode is somewhat broken a little in terms of ext4 support. It can mount ext4 partitions successfully. But its e2fsprogs package (tune2fs, e2fsck etc.) doesnt see ext4 partitions and say, that superblock is corrupted on a partition once is converted to ext4 (at least it did it for me. May be I should force filesystem type with -t ext4 switch?). Keep in mind, that if you screw your system up too badly, you will not be able to run tune2fs and e2fsck on it from rescue modeBut you will still able to mount it if it is not corrupted badly. In all below examples,Boot your system normally and login as root. Upgrade kernel if you wish (I usually use yum upgrade to upgrade all on new machines). Then upgrade/install some other packages
I am attempting to run a fsck on a number of large ext3 filesystems. I am doing this proactively because I want to minimize reboot time and the filesystems are past the interval time of 6 months. When I run the command " fsck -f -y device" I get the following error on all of the filesystems-
fsck 1.39 (29-May-2006) e2fsck 1.39 (29-May-2006) fsck.ext3: Device or resource busy while trying to open /dev/mapper/mpath0p1
I am unable to boot my server and it is erroring with the message "Kernel panic - not syncing: Attempted to kill init!". Here are the details:
I have a brand new Dell PowerEdge T110 server with Quad-Core Xeon CPU and 2GB 1333MHz RAM. I have installed a hard disk (SATA, 7.2rpm) on this machine that I removed from another Dell PowerEdge T100 server with Dual-Core Xeon CPU that was running software RAID 1.
Now when I boot the new T110 server, it displays the following error messages code...
I am running CentOs v5.5 x86-64. If I put the hard disk back into T100, it boots fine. I do not know why it is not working with T110 server.
I am going to install CentOS 5 on my pc , for3d modeling , and i have some doubts about partitioning the system.
I know that i can have /, /var , /tmp , /home and other directories as individual partitions. I know that i can use ext3 , or xfs ( i know that anaconda doesn't let to use xfs, but i know a way of migrate partitions to xfs after installing) or ext4 , and others , without problems.
But i could for example, once installed all with ext3 , have for example / on ext3 , and /var and /home on xfs.
For me it would be very interesting have /home in a another partition and as xfs (migrating it later from ext3) as mostly i will save in /home a lot of big files ,images,dvd isos,renders , binary maya files and like, and i see a advantage of use xfs with /home.
But a lot of people also use xfs for / as well , but as / has a lot of small files , perhaps use xfs on /var and some other directories, could be good (because xfs performance deleting files or other features), and leave / as ext3 for example.
So is it possible to have different filesystem type for some directories under / ,(for example /var and /home as xfs, the rest as ext3 in / ) , without having any problem ?
(not counting using xfs for a directory that won't see improved his performance because has a lot of static small files or like)
My dvd is broken. I always failed to install centos from network because of wrong configuration of tftp server. I'd like to install centos from harddrive. I got a litle application named grub4dos, I try to use it but never succeded. Therefore, I have tow questions:
1. How to install Centos from / through hard drive? 2. Where should I put the Iso file of centos or centos installation files, if i use grub4dos.
first of all, ill provide you with the package name i got [URL]...i went to /usr/src/redhat/SOURCES/bwbar-1.2.2 did ./configure ; make
then i get this problem : [root@server bwbar-1.2.2]# ./bwbar ./bwbar: /usr/local/lib/libpng12.so.0: no version information available (required by ./bwbar) i have installed libpng & libpng-devel
after looking around a bit i thought it would be better to get the sources from kernel.org directly and try to compile that one, but then i found it to have the exact same error. would be very nice if someone could direct me to a solution for this. i have the bwbar already installed on another server which runs CENTOS 4 , i installed it there AGES ago , so i dont really remember what was my method back then.
the CENTOS 5 server dose not like me installing bwbar on it for some reason. maybe its bwbar's fault?, im no coder so i hope anyone that got a clue could check this out for me.
it seems the skype not working as i was unable to see this user's status as logged in from another skype account on a different system the architecture is: CentOS release 5.3 (Final) uname -r : kernel- .6.18-128.1.6.el5 uname -a: Linux localhost.localdomain 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:19:18 EDT 2009 i686 i686 i386 GNU/Linux
I installed the latest version of Centos 5.4.It came with Xen version 3.0.2 I think.I am running it on a Dell R510. It supports hardware virtualization.I was able to virtualize Windows XP and Windows 2003 server on it by selecting the install from DVD option.I was having problems trying to get a PCI DekTek card seen by the virtualized Windows domains so I tried to upgrade XEN to 3.4.2.I used the repos available from Gitmo and it went easy.
The only problem is now that when I try to create a "New virtual host" it only allows me to use HTTP, FTP option and not the iso or DVD option. They are greyed out. I was wondering if anyone has had this problem and might know a work around for the Xen 3.4.2 problem. Perhaps a better location for the kernel or something.
Agere got purchased by LSI and now LSI tech support claims there is no Linux driver for this card even though the literature clearly states the availability of a Linux driver.I have installed the firewire driver mentioned in other forum posts from ELRepo.
I have configured a "Syslog" server on /var directory as a separate ext3 partition - to receive the logs and events from the clients & the firewall as well. The directory needs to grow dynamically as the logs are populated. Is there a way i can make the filesystem grow dynamically as and when the directory is full.
I am hosting a few customer servers now, all of which are virtual machines running on a CENTOS 5.x host. Each Centos host has a couple of extra drives. When I formatted them ext3 they automatically had a schedule of a full forced fsck after 6 months. Do I really need to do that check regularly? It results in a fairly large outage since my disks are each 1TB and there are up to three extra drives on each server. I try to reboot these servers every 6 months but this part adds a large amount of time to a routine reboot.
I have more than a dozen servers running CentOS (mostly supermicro servers) everytime i do mkfs.ext3 or mkfs.ext4, it always hangs the server (nothing is responding, not even the terminal) can't even do Ctrl+C to kill it. but the funny thing is, if i leave it on for hours, it'll finish eventually.
this puzzles me, i've tried so many different SATA drives and different servers, different kernels, different CentOS. for example purposes, my CentOS 5.3 runs 2.6.18-92.1.13.el5 kernel. i also have 5.4 and 5.5. mkfs.ext3 works fine on SAS, but always hangs on SATA. here's where it usually hangs Writing inode tables: 2126/7453
I am using CentOS 5.5.I suppose this is an oft repeated question. I accidentally deleted, using rm command, 2 wmv files. The files were in a single ext3 1Tb drive, with just 1 partition --- the ext3 one. Each file is 600 - 800mb. The 1Tb drive has only about 20Gb data.Immediately after deleting the files i unmounted the drive (/dev/sdc1). Thereafter i searched the the net and came to know of the recovery tools foremost and photorec. I have installed both of them. I am currently running both of them as root --- foremost is just showing a lot of * signs on the terminal and photorec has managed to find some txt and png files --- but no wmv.For foremost i used: /usr/sbin/foremost -t wmv -i /dev/sdc1For photorec i followed some instructions available on the web.
In the meantime, based on some post on the net i ran debugfs as root, then cd into the directory where the files were deleted. Then on typing ls -d i managed to get the inodes of the 2 deleted files and the names of the deleted files are also correct. The instructions on the net http://www.theavidcoder.com/?p=3 tell me to run fsstat and dls both of which i am unable to find in /bin, /usr/bin, /usr/sbin and /sbin. So i am unable to proceed further.
