Strange file system problems

Mike_305 — Wed, 28 Aug 2002 21:55:48 GMT

Hi,

We have a file system called /test/test.mc and the problem that I am running into is when I reboot the system this one file system doesn't get mounted automatically. I can mount manually without any problems. I can cut and past the entry from fstab and tested out the syntax on our test system to make sure it???s correct or not and it works fine on test system and the same syntax doesn???t work on my production system.

Also, when I do mount ???v command it shows that it???s using ???log??? instead of ???delaylog???.

Entry in fstab is as below:

/dev/vg01/lvol1 /test/test.mc vxfs rw,suid,nolargefiles,delaylog,datainlog 0 2

And mount ???v reads:

/dev/vg01/lvol1 on /test/test.mc type vxfs log on Sat Aug 24 11:53:3 8 2002

If I do ???umount ???a??? all the file systems gets unmounted but ???mount ???a??? this one file system doesn???t get mounted.

Thanks in advance.

Thanks,

Mike

Please post your entire fstab because I want to see when /test is mounted.

Hi Mike,

What does lvdisplay -v /dev/vg01/lvol1 show?

Do this before you manually mount.

I'd suspect a problem with the LV. Maybe even something obscure like a dupe minor number. Check your /dev/vg* dirs thoroughly.

Also check you /etc/lvmrc file in case it's excluding it.

Jeff

Hi Harry,

Their is no /test mount point, when I created this file system, the way I did is in sam where is says mount point, I put /test/test.mc

Thanks,

Mike

Mike,

/test exists, right?

Also, the paste was just screwed up, the fstab file doesn't look like that at the end of the file does it?

When you do a

vgdisplay -v vg01

what does it return??

what does

ls -l /dev/vg01

return ??

Hi Mike:

The 'delaylog' mount option requires the Online JFS license. If you do not have this Online component, I would expect the mount operation to fail.

Hi,

Sorry Harry could not get back to you last night.

I have other file system with the same type of setup, for example /test/ora and they mount fine, with out any problems.

The question that I have is in /etc/fstab file its define as delaylog and when I run ???mount ???v??? command it shows ???log??? not delaylog? When I compare with other file systems if the file system is define as delaylog then in ???mount ???v??? output it shows delaylog. Any idea.

Entry from fstab;

/dev/testmcvg/testmclv /test/test.mc vxfs rw,suid,nolargefiles,delaylog,datainlog 0 2

Entry from ???mount ???v???

/dev/testmcvg/testmclv on /test/test.mc type vxfs log on Sat Aug 24 11:53:38 2002

Mike,

Have you looked in your /etc/rc.log file to see if there are any error messages at boot when the rc scripts try to activate the vg01 volume group and mount that filesystem? Also, check your /etc/lvmrc file and see if the AUTO_VG_ACTIVATE is set for 1 or 0. If you have that off, you will need to add an entry in the custom_vg_activation function at the bottom of the lvmrc file. Usually you see this on boxes in a ServiceGuard environment. It catches me here every so often.

Hi John,

Looking at /etc/rc.log it doesn???t like mount option. I am not sure what mount option are incompatible.

AUTO_VG_ACTIVATE=1

and rc.log has this entry;

mountall: cannot mount /dev/testmcvg/testmclv
mountall: diagnostics from mount vxfs mount: mount option(s) incompatible with file system /dev/testmcvg/testmclv
checking quotas

Thanks,

Mike

Re: Strange file system problems

John Poff — Thu, 29 Aug 2002 18:23:43 GMT

Mike,

Two questions. First, (back to James' point earlier), are you running Online JFS on this system? Does 'swlist -l bundle | grep -i jfs' return something like this:

B3929BA B.11.00 HP OnLineJFS (Advanced VxFS)

Second, did you create the filesystem as a vxfs filesystem? (newfs -F vxfs /dev/vg01/rlvol1)

(I typed in this reply once and hit submit and it never showed up, so I'm trying it again.)

Re: Strange file system problems

Jeff Schussele — Thu, 29 Aug 2002 18:31:02 GMT

Hi (again) Mike,

Are you able to activate/deactivate the VG w/o incident?
If you

vgchange -a y /dev/testmcvg

Does it activate OK. If not & it's possibly been in an MC/SG cluster you may need to

vgchange -c n /dev/testmcvg

To make in cluster unaware.

Also I'm not sure if this can cause the problem you're seeing, but I'm wondering if it had been set FOR largefiles at some point in the past - try this

fsadm -F vxfs -o nolargefiles /dev/testmcvg/testmclv

To insure it's set for nolargefiles.

Rgds,
Jeff

Re: Strange file system problems

Mike_305 — Thu, 29 Aug 2002 19:58:26 GMT

Hi John,

Yes, I am running online JFS.

B3929BA B.11.00 HP OnLineJFS (Advanced VxFS)

Yes, it's a VXFS file system.

When I do "fstyp ???v /dev/testmcvg/testmclv" shows as vxfs file system. I am not sure how this file system was created but fstyp reports as vxfs file system.

No cluster is running on this system.

Yes, it???s set as nolargefiles.

FSTAB entry:

/dev/testmcvg/testmclv /test.mc vxfs rw,suid,nolargefiles,delaylog,datainlog 0 2

Thanks,

Mike

Re: Strange file system problems

John Poff — Thu, 29 Aug 2002 20:10:38 GMT

Mike,

I've gotten bitten by /etc/fstab entries before also. I remember working through it by going back to the simplest entry for the filesystem and trying 'mount -a' on it. If that worked, I unmounted the filesystem, edited the fstab file, added another option, and tried mounting it again until it blew up.

At least that might point you to the particular option that 'mount' doesn't like. I'm betting on the largefiles option.

Re: Strange file system problems

James Murtagh — Thu, 29 Aug 2002 20:30:05 GMT

Hi Mike,

This usually happens when the filesystem mount options in the fstab conflict with how the filesystem is set up. Can you confirm largefiles is not set on by running :

fsadm -F vxfs /dev/vg01/rlvol1

If this is OK, try mounting the filesystem manually then remounting with :

mount -F vxfs -o remount /dev/vg01/lvol1

Then try unmounting and run mount -a to see if this worked.

When you are mounting this manually, what options are you specifying? If you are not using any, the system will use the defaults, which is probably why you have "log" option after running mount -v.

Regards,

James.

James R. Ferguson — Thu, 29 Aug 2002 20:55:50 GMT

Hi Mike:

To see the largefile bit setting unmount the filesystem and do:

# fsadm /dev/vg01/rlvol1

Either 'largefiles' or 'nolargefiles' will be returned.

Regards!

Re: Strange file system problems

Mike_305 — Thu, 29 Aug 2002 21:53:18 GMT

Hi,

I got the answer to the problem. Thanks to all of you. YOU GUYS ARE GREAT.

When I do ???fsadm /dev/testmcvg/rtestmclv??? it reports as below.

nomultifsets
largefiles

and in /etc/fstab it???s marked as ???nolargefiles???, I think that is the problem.

On my next reboot I will change the entry and test the mount point out.

Once again thanks for your help in testing this issue.

Thanks,

Mike
