EXT2 Error

[drakebasher]

Following is posted on behalf of jmt:

I had the following error message:

EXT2 -fs error (device ide0(3,Cool): ext2_check_page: bad entry in directory #2: inode out of bounds -offset=0, inode=4915457, rec_length=148, name_len=0

Currently, I can not see the files under my primary directory. When I do an ls nothing comes up. When I do a df it shows that that directory is 47% full.

Can you help me resolve this problem,

Thanks,

Matt

Assuming that the partition is actually an ext2 filesystem, it looks like it must be corrupt. I would run fsck on the filesystem, but that must be done with the partition umounted. If it is your root ( / ) partition, you will need to boot in 'single' mode, or use your install CD in "rescue" mode. If this isn't clear, please post what distro you have, is it a new install or have you been using it for a while and if you have an idea what caused this.

We use this machine more as a file server but it also housed our inhouse database. The machine has been up for more than a year and we haven't had any problems until this week. I can see into other directories except our primary directory - Public. Here is how we have it set up:

Can you post the result of the command 'mount' ?

[jmt]

root@lsl://# mount

/dev/hda1 on / type ext2 (rw)
/dev/hda5 on /var type ext2 (rw)
/dev/hda6 on /home type ext2 (rw)
/dev/hda7 on /usr/src type ext2 (rw)
/dev/hda8 on /public type ext2 (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
proc on /proc type proc (rw)
usbfs on /proc/bus/usb type usbfs (rw)

[drakebasher]

I would try to umount and fsck the public partition:

umount -l /dev/hda8
fsck /dev/hda8
mount /dev/hda8 /public

[jmt]

Will do,

Thanks, I'll let you know how it turns out,

I ran the fsck operations with mixed results. All files were renamed with a preceeding # sign followed by a numeric name. Some of the files were retreived in good shape others weren't.

Thanks for all your help, now comes the task of recovering everything.

I would take the time if you can and backup and switch filesystems EXT2 is very dated and really should not be used same with EXT3 (yes i know they are well tested but so is reiserfs V3) maybe use jfs/xfs for the database partition (i say this cause there good at large file handling reiserfs is the opposite) and reiserfs for the rest..
