Mount point not visible

[Musa I. S.]

Hello,

one of my mountpoints /applprod1 is not visible. this happened after the systems went off. please view attachment for bdf, fstab, lvmtab and mnttab.

[Jeeshan]

mount it manually
#mount /dev/vgapplprod1/applprod1 /applprod1


but before that verify that the vg is not offline

#vgdisplay -v vgapplprod1

if its in offline then turn it to online and then mount.

[Musa I. S.]

hello,

below is the response i got when i tried to mount manually.


HQ-DEVP:/#mount /dev/vgapplprod1/applprod1 /applprod1
mount: /dev/vgapplprod1/applprod1: No such file or directory

[Jeeshan]

did you try this command?

#vgdisplay -v vgapplprod1

[Musa I. S.]

Yes i did. the status reads available.

[Jeeshan]

if so than check that the applprod1 folder has been exist in / file system. if not exist than create it and mount again.

[Musa I. S.]

there are two mount points applprod1 and applprod2. Please view the output below. the owner is different...

drwxrwxrwx 3 root sys 96 Jun 25 16:14 applprod1
drwxr-xr-x 6 root root96 Dec 24 2007 applprod2

[Jeeshan]

so, can u mount it?

or ownership discard you?

[Musa I. S.]

i still cannot mount it.

Hi Musa this is your /etc/mnttab file:

Post "vgdisplay -v /dev/vgapplprod1"

Check if the lvol device file for applprod1 exists. Post "ll /dev/vgapplprod1"

Hi Musa,
have you inserted the following row:

/dev/vgapplprod1/applprod1 /applprod1 vxfs ioerror=mwdisable,delaylog,dev=400100
01 0 0 1215425043

on your /etc/mnttab file?

Best regards.
Ernesto

< EC: have you inserted the following row ...on your /etc/mnttab file?

You do not edit the mnttab file. It is a dynamic file that is created by the mount command during bootup and during any subsequent mounts.

The problem is the name of the LV volume. You are using /dev/vgapplprod1/applprod1 in your /etc/fstab but the actual name of the logical volume is

LV Name /dev/vgapplprod1/lvapplprod1

Edit your /etc/fstab file and correct the name and then issue a mount command

"mount /applprod1"

This way the spelling of /etc/fstab is also verified for the new edited entry.

TTr,

Thank you very much. In addition to solving my problem, u made me understand mnttab.

Thank you.

[Musa I. S.]

thanks.
