Quote Postby troysunix » 2011/02/01 05:19:14 My first thought is that you can't have a volume label larger than 16 characters (see e2label manpage). Your 'fsck' error shows a

volume label of 17 characters. Your problem is likely that you have an entry in /etc/fstab similar to: LABEL=/opt/server-conf/ /opt/server-conf/ ext3 defaults 1 2To resolve the issue, log in as root. You will likely need to remount '/' as read write: /bin/mount -o remount,rw /Then simply update /etc/fstab, stripping the last '/' from "/opt/server-conf/": LABEL=/opt/server-conf /opt/server-conf/ ext3 defaults 1 2After writing 'fstab', reboot and you should be fine. For curiosity, I set your label to one of my disks on a test host and checked it, verifying the label was truncated: tux [0] tune2fs -L /opt/server-conf/ /dev/sdc1 tune2fs 1.39 (29-May-2006) Warning: label too long, truncating. tux [0] tune2fs -l /dev/sdc1 | grep name: Filesystem volume name: /opt/server-conf Top pschaff Retired Moderator Posts: 18276 Joined: 2006/12/13 20:15:34 Location: Tidewater, Virginia, North America Contact: Contact pschaff Website HELP!!!fsck.ext3 ERROR!!!

April 10, 2012 in Data recovery, Debian Linux, Gentoo Linux, RedHat/Fedora Linux, TipsLinux comes with the system utility fsck ("file system check") for checking the consistency of a file system. This quick post linux fsck on boot explains how to use fsck to fix error. The syntax is as follows
Fsck Mounted Partition
to check and optionally repair one or more Linux file systems:
fsck Fs-Name-Here fsck /dev/xyz fsck /home fsck.ext3 /dev/hdc1 fsck.ext2 repair filesystem 1 # /dev/flash/device/nameFs-Name-Here can be one of the followingA device name (e.g. /dev/hda1, /dev/sda2, /dev/md0, /dev/vg1/volume_1)A mount point (e.g. /var, /home)An ext2 label (e.g. LABEL=home )UUID specifier (e.g. UUID=8868abf6-88c5-4a83-98b8-bfc24057f7bd)ExampleFirst, a file system must be unmounted. http://www.centos.org/forums/viewtopic.php?t=13254 You cannot repair it while it is running. Take system down to runlevel one (make sure you run all command as root user): # init 1Next, unmount file system, for example if it is /home (/dev/sda3) file system then type command: # umount /home OR # umount /dev/sda3Finally, run fsck on the partition, enter: # fsck /dev/sda3 However be sure to specify the file system type using http://www.cyberciti.biz/tips/repairing-linux-ext2-or-ext3-file-system.html -t option. Recently, one of our sys admin run the command on ext3 file system w/o specifying file system. Result was more corruption as fsck by default assumes ext2 file system: # fsck -t ext3 /dev/sda3 OR # fsck.ext3 /dev/sda3 OR # fsck.ext4 /dev/sda5 If you do not know your file system type then typing mount command will display file system type. $ mount Sample outputs:/dev/root on / type ext4 (rw,relatime,barrier=0,journal_checksum,data=ordered) /tmp on /tmp type tmpfs (0) none on /dev/pts type devpts (gid=4,mode=620) /sys on /sys type sysfs (0) /proc/bus/usb on /proc/bus/usb type usbfs (0) /dev/vg1/volume_1 on /volume1 type ext4 (usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,synoacl) /volume1/@optware on /opt type bind (bind) none on /proc/fs/nfsd type nfsd (0) fsck will check the file system and ask which problems should be fixed or corrected. If you don't want to type ‘y' every time then you can pass -y option to fsck: # fsck -y /dev/sda3 Please not if any files are recovered then they are placed in /home/lost+found directory by fsck command.Don't execute, just show what would be done: # fsck -N /dev/sda3Once fsck finished, remount the file system: # mount /homeGo to multiuser mode, enter: # init 3 Read man page of fschere for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow http://unix.stackexchange.com/questions/140688/rhel-server-booting-problem-fsck-ext3-unable-to-resolve-label-u01 the company Business Learn more about hiring developers or posting ads with us Unix http://serverfault.com/questions/283331/is-there-a-way-to-ignore-the-fsck-ext3-unable-to-resolve-label-error-during-t & Linux Questions Tags Users Badges Unanswered Ask Question _ Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.

The problem is that when one of disks missing, the server when booting up, displays the following error: fsck.ext3: Unable to resolve LABEL LABEL is one of the missing disks partition - boot and / RAID1 partitions seem to work fine. Is there any configuration to ignore these errors, and just bring the server online? So if there one of disks missing, the server will ignore any errors, and just will continue booting? linux raid boot fsck share|improve this question asked Jun 23 '11 at 9:26 SyRenity 1,40953970 1 Why would you want to ignore an error that reminds you that your array is degraded? Why not just, say, fix the problem instead? –Ignacio Vazquez-Abrams Jun 23 '11 at 9:33 1 Point is that it more easy/faster to re-provision the server for us, but we do want to safely migrate the data from it. –SyRenity Jul 9 '11 at 21:46 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted The problem is that the partition in question is marked for fsck to check on boot. It is the sixth field (the last one) in /etc/fstab, referred to as "pass" or "fs_passno". If this field is present, and is not 0, it indicates the order in which filesystem checks are done at boot time. So, either remove that column from the fstab file, or replace it with 0, like this: LABEL=the_label /the/mount/point ext3 defaults share|improve this answer edite
