Missing filesystems

MarkSyder — Thu, 06 Jan 2005 08:34:41 GMT

Hi everybody.

I've just restored a new disc with apparent success.

I have one remaining problem: the filesystem on this disc is called /ha1. I have other filesystems called, for example, /ha1/ugs200, on a different disc. Now that I've regained access to /ha1 the system can no longer see these other filesystems. I'm sure there must be a simple command to bring them back. Anyone know what it is?

Mark,

Have you tried "mount -a"?

I'm not sure, but If I understand, you have mounted a fs at some point under wich other mount points exists...

You should umount /ha1, then unmount any fs mounted under /ha1, and remount anything in good order : first /ha1, then /ha1/ugs200, then /ha1/ugs200/xxx.

Regards,

Fred

Hi Mark,

Do you get an error executing "mount -a" ?

What do you mean with "the filesystem on this disc is called /ha1"?

Do you mean there is a file system on this disc that you've mounted to the directory (mountpoint) /ha1 on your root file system?
If this is the case and before mounting the new filesystem to /ha1 there was something below /ha1 (e.g. ugs200) you'll no longer see it, that's right.
So you first should unmount /ha1 again and either mount it to another mountpoint (e.g. /ha2) or unmount all that is under /ha1 and mount the filesystems in the correct order - as mentioned before.

Sounds like you mounted /ha1 on top of /ha1/ugs200.

umount /ha1

umount /ha1/ugs200

mount /ha1
mount /ha1/ugs200

Thanks everyone.

Advice from HP: mkdir /ha1/ugs200
mount /dev/vg02/lvolx /ha1/ugs200

worked fine, the users are logged in, and I'm off the hook!
