fsck error

agvenkatesan — Mon, 19 Nov 2007 09:20:16 GMT

hi all

while running fsck for a vxfs file system following error is displayed

# fsck -F vxfs -o full -y /dev/vgxx/rlvolname

1)vxfs fsck : filesystem had a i/o errors on userdata
2)log replay in progress
3)pass0-checking structral files.
4)pass1-checking inode sanity and blocks
5)fileset 999 primary inode 2 marked bad,allocation flags (0x0001)
6)file set 999 primary inode 2 failed validation clear? (YNQ)Y
7)root inode for file set 999 is invalid
8)full file system check required, exiting....

if i give NO option in point 6 it is going inside for inode checking for about 45000 inodes asking for confirmation check for each and every inode, to give YES/NO option is something which is very tedious job. plse help me to solve this.

regards
venkatesan

Hi,

Seems like FSCK is unable to correct the FS corruption !!.

see if you can run fsck with nolog ..

fsck -F vxfs -o full,nolog -y /dev/vgxx/rlvolname

what is the OS version/Vxfs layout
run fstyp .....
fstyp -v /dev/vgxx/rlvol...

RD

Venkat,

Please install the latest fsck patch

PHCO_23651 11.00 fsck_vxfs(1M) cumulative patch

a few known issue:=
PHCO_23651: CORRUPTION
A significantly fragmented VxFS filesystem may
be corrupted by fsck_vxfs(1M). Two consecutive
invocations of fsck_vxfs(1M) can result in a
directory corruption.

hi all,

I have downloaded and installed the patch PHCO_23651 and depended patches. after installing it is asking for kernal rebuilding at the end, task is suspended due to following errors found in the log file.

make faliure

error: the command "usr/sbin/mk_kernel, which is used to rebuild the kernel, has failed. becoz kernel related filesets were installed. this command must be executed by "swinstall"
without failures, before the load can continue. check the above output for the failure.

note : the installed phase has suspended. check above out put for reason.

please give your inputs to resolve this.

thanks & regards

venkat,

run check_patches to see what kind of errors you face.

i suspected your reinstall PHKL_18543, this will cause kernel unable to regen.

check this doc of how to recover it
