File system problem

Joseph Bague — Wed, 18 Feb 2004 05:49:21 GMT

Hi to all,

Something weird happening in my B2000, I am running this command but there is no output.

mkfs -F hfs -m /dev/vg00/lvol1

Any idea what is the problem? BTW it is hp-ux 11.00

Regards

Joseph

First check doing

#vgdisplay -v vg00

and check whether vg01 is already used.

check /var/adm/syslog/syslog.log

TGM and Joseph

are you awake :-) think it is /stand

Is your system still running ? if it is do NOT reboot.

Could you check if your still have a kernel in /stand.

# ls -la /stand

I think you should be using newfs;

newfs -F hfs /dev/vg00/rlvol1

Hi T.G.

There is no other vg on that machine other than vg00, and vgdisplay output seems to be fine.

Robert,Now I am awake,

by default lvol1 in vg00 is taken by the /stand file system.

why are you doing a newfs on that

Joseph, I meant lvol1 and not vg01 in the previous post!

Hi Robert

I try this command to my other server this is the sample output.

mkfs -F hfs -L /dev/vg00/lvol1 516096 28 12 65536 8192 16 10 60 10366

I am wondering why is there no output on b2000 (hp-ux 11.00).

Joseph

Hi Robert

/stand is still intact.

Joseph Bague — Wed, 18 Feb 2004 06:18:18 GMT

according to man mkfs

-m Display the command line that was used to create
the file system. The file system must already
exist. This option provides a means of
determining the parameters used to construct the
file system.

Hi,

as SEP said, why don't you use newfs?
It is better than mkfs, less options, less customizations, less problems:

newfs -F hfs /dev/vg00/rlvol1

Try this command, does it work?

Best regards,
Ettore

Hi Ettore

I am not trying to format lvol1, what I am trying to do is get some parameter.

Regards

Fabio Ettore — Wed, 18 Feb 2004 06:55:03 GMT

Ah....then I understand anything about other posts! :-(

Well, then use

# fsadm -F hfs /dev/vg00/rlvol1
# fstyp -v /dev/vg00/lvol1

Otherwise what is the parameter you are looking for?

Best regards,
Ettore

Hi

What really happened is my ignite backup is failing, then I send the make.rec1 log to hp engineer. They said ignite backup is calling this command
"mkfs -F hfs -m /dev/vg00/lvol1" (maybe the output is used in automatic recovery script of ignite)which in my b2000 has no output that cause ignite to fail.

have you tried booting your system in maintenance mode and fsck /stand ?

Fabio Ettore — Wed, 18 Feb 2004 08:18:46 GMT

Ok Joseph, in order to restrict possible reasons of the problem:
Does mksf work on other filesystems?
Launch it on another filesystem (of course on the same system):
- if mkfs obtains an output then problem is about filesystem; also try other commands (e.g. fstyp or fsadm as I said in my last post);
- if mkfs doesn't obtain an output on other filesystems too then check mkfs size;
# ll /usr/sbin/mkfs
I had a similar problem where a command (I don't remember what it was) was obtaining no output, problem was that it had size 0!

Well, just a thought.... check size of your mkfs. On a my HP-UX 11.00 system I obtain
# ll /usr/sbin/mkfs
lrwxr-xr-x 1 root root 16 Mar 5 2003 /usr/sbin/mkfs -> /sbin/fs_wrapper

What about yours?

Best regards,
Ettore

Hi Ettore

My answer,

Does mksf work on other filesystems?

--yes, i tried it on /tmp

- if mkfs obtains an output then problem is about filesystem; also try other commands (e.g. fstyp or fsadm as I said in my last post);

-- I tried the fstyp and fsadm on /dev/vg00/lvol1 its ok.

Robert,

Not yet. How can i do it? Does hp-ux mount the /stand on maintenance mode?

Regards
Joseph

sorry Joseph if I continue... can you post output of

# ll /usr/sbin/mkfs
# ll /sbin/fs_wrapper

mkfs is linked to fs_wrapper. Check if fs_wrapper or mkfs have size 0. I don't think that it is the problem because mkfs on /tmp filesystem works. I just ask you that for more informations on problems.

Best regards,
Ettore

Since you are just querying the lvol, then it should work but you might try using the raw volume name (rlvol1 not lvol1). Also, what does the command: lvlnboot -v report? Any problems? Since lvol1 (/stand) is only used for bootup and for building a kernel, first run a backup (just 50-100 megs)then run fsck as in:

umount /stand
fsck -F hfs /dev/vg00/rlvol1
mount /stand

There may be some filesystem corruption causing the hang.
