disk missing or F.S. corrupted

[uadmin_1]

Hi FR,

can you rerun fsck with -m option so it will return error code due to that error code (0, 32 or 33) we may get some idea about file system status.

# fsck -F vxfs -m -y  <lv path>

Hi Raj!

If I try your suggestion:

#fsck -F vxfs -m -y /dev/vg01/lvol7
vxfs fsck: sanity check: /dev/vg01/lvol7 needs checking

If I do what did previously:

fsck -F vxfs -o full -y /dev/vg01/lvol7
file system is larger than device
vxfs fsck: cannot initialize aggregate
file system check failure, aborting ...

Hi Fernando:

man pvck

pvck should only be run on a device whose volume group has not been  activated.

# pvck -n /dev/rdsk/c4t0d3

verify output and

# pvck -y /dev/rdsk/c4t0d3

rgs,

Hi Fernando:

http://h30499.www3.hp.com/t5/System-Administration/need-help-finding-where-extents-are-coming-from/m-p/3969311/highlight/true#M292831

rgs

[NDO]

did you want me to run that comand specifically to c4t0d3 or any other that I suspect has the problem, for example when I do pvdisplay c43t0d5 shows that the disk is free

F.R.

[uadmin_1]

Hi FR,

have u ran any lvextend command on that lv ?

if you ran lvextend and doestn't ran fsadm then there is a chance to get this kind of problem.

if above is not the case then try below process

step 1: take backup of /etc/lvmtab
step 2: vgscan -v -p     # see weather it is throwing any action required message
step 3: vgscan -a        #
step 4: check with lvdisplay and vgdisplay
step 5: if anything wrong  with old configuration then replace /etc/lvmtab file with backup file ( Step 1 result file )

Regards,
Raj

[rariasn]

Hi Fernando:

# vgchange -a y vg01

Put output from the comand

# vgdisplay -v vg01
