vxfs mount: /dev/vg02/lvol1 is already mounted, /oracle is busy, or allowable number of moun

naveennella — Mon, 31 May 2010 12:38:52 GMT

I have a problem with a disk that is damage and belongs to the vg02 volume group.

The filesystems that are unable to be mount are /oracle
What will be the procedure to can recover these filesystem ?

# mount -a
vxfs mount: /dev/vg02/lvol1 is already mounted, /oracle is busy,
or allowable number of mount points exceeded
mount: /dev/vg00/lvol8 is already mounted on /var
mount: /dev/vg00/lvol7 is already mounted on /usr
mount: /dev/vg01/lvol2 is already mounted on /usr/sap
mount: /dev/vg00/lvol6 is already mounted on /opt
mount: /dev/vg00/lvol5 is already mounted on /home
mount: /dev/vg00/lvol4 is already mounted on /tmp
mount: /dev/vg00/lvol1 is already mounted on /stand

It says the above message..is there any way to recify that.we dont have any back up of this.please suggest me how to solve the issue..?

regards,

Naveen

See

http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad_WP.pdf

Don't have a backup? Bad luck.
You should learn the lesson and backup your systems.

Check it

# fsck -F vxfs /dev/vg02/rlvol1

and follow the document I posted earlier.

Dear Expert,

# fsck -F vxfs /dev/vg02/lvol1
vxfs fsck: file system had I/O error(s) on meta-data.
vxfs fsck: file system had I/O error(s) on user data.
vxfs fsck: fsck read failure bno = 13092100, off = 0, len = 8192

This is the output i got..

Do the "dd" check (see manual above).

Hi Naveen:

Try a full check (as the last error suggested):

# fsck -F vxfs -o full /dev/vg02/rlvol1

However, as Torsten has suggested, look at "When Good Disks Go Bad" guide. You are probably going to need to replace the damaged disk and unless it's mirrored, restore the missing data from a backup.

Regards!

Dear Expert,

# fsck -F vxfs -o full /dev/vg02/lvol1
vxfs fsck: file system had I/O error(s) on meta-data.

vxfs fsck: fsck read failure bno = 13092100, off = 0, len = 819

I read that document and checking everything it says ok and good,but i cant understand where it goes wrong.

Did you perform the "dd"? How? Results?

>I can't understand where it goes wrong.

fsck(1m) says it is bad.
And if you use dd(1), you should do the whole disk, not just 64 Mb.

For whatever reason /dev/dsk/c5t0d1 is not accessible.

This is a hardware RAID (mirror) built from a RAID4SI controller, so follow the advise above and check the controller.

As said,

# irdiag -v

will surely show the reason for this problem.
