fsck fail

[Yarok]

Hello,

Thank you for the correction. Indeed, it is

LVOL9 and not LVO19.

I could not find /scc and /dev/vg00/lvol9 as well.
I checked the mount to /dev/vg00/lvol9 and it says that its not in /etc/mnttab

bdf check olso indicates that /dev/vg00/lvol9 does not exist.

/etc/exports shows:

/scc -annon = 0
/disk2/scc = 65534

I compared with Other HP machine and it shows that /dev/vg00/lvol9 is mounted to /scc and
/etc/exports shows

/scc -annon = 65534
/disk2/scc = 65534

Please note that /scc is necessary for work.

Please advice.

Your previous fsck command was directed to LVOL 19, which apparently does not exist. No wonder it failed.

This command will try to fix LVOL 9, accessing it in raw mode. For this command, the VG must be activated, but the LVOL must be unmounted. If I understood correctly, that's exactly the situation you have now.

/sbin/fsck -F vxfs -o full /dev/vg00/rlvol9

If the filesystem check is successful, you should be able to mount the LVOL 9 filesystem after that:

mount /dev/vg00/lvol9

If this is successful too, it should be possible to reboot (with the command "shutdown -r now") and have your system start up normally again.

The original error message (cannot read block ...) suggests your disk may have already failed partially and may soon fail completely. If you don't have a backup of the system, make one as soon as possible.
(I hope you *do* have a backup: some files may already have been lost or damaged)

If you have a support agreement with HP, open a support call for disk replacement, let the HP engineer fix it and ask him/her how to proceed.

If you don't have a support agreement, please read this HP document called "When Good Disks go Bad: dealing with disk failures under LVM":

Sorry, but the fsck cannot be start. I think, again ,it concerns to the reason that there is no LVOL9.

Any idea how to search for the vol?

>the fsck cannot be start.

What error did you get?

>Any idea how to search for the vol?

What do these show:
ls -l /dev/vg00/lvol9
/sbin/lssf /dev/vg00/lvol9

[Yarok]

The error I get is:

vxfs fsck: cannot stat /dev/vg00/rlvol9

ls -l /dev/vg00/lvol9 shows:

/dev/vg00/lvol9 not found


/sbin/lssf /dev/vg00/lvol9 shows:
lssf: no shuch file or directory /dev/vg00/lvol9

Please provide the output of

vgdisplay -v vg00

If it is too long, please DO NOT copy paste here; but attach.

Hello again,

Sorry for the delay but I was out of the office.

I attached 2 files:

LVOL_check - is the vgdisplay -v vg00 resault of the "demaged" computer

and

LVOL_check_OK - is the vgdisplay -v vg00 command resault of other "good" computer(an HP similar machine that does not suffer from disk problem).

[Yarok]

Ho,

I can see that only one file canbe attached at a time. so here is the second one (LVOL_check_OK)

[Dennis Handly]

>only one file can be attached at a time.

Yes, unless you tar and/or zip the files.
(If you zip, make sure the suffix is .Zip.)

[Yarok]

Can someone give me a solution to this problem?
In my poor opinion, I should recreate the lost Volume - (Vol19).

1. How can I do that?
2. How can I restore the lost information? (I think the information is still there, somewhere, I need to check for it).
