Unable to mount Metadevice
Hi,

I am running Solaris 8 on a V880 which has recently crashed. It has got a fibre connection to a StorageTrek array containing my database info. Since the crash I have been unable to mount the 2 metadevices which correspond to /spool & /apps - these FS's contain my db info and theredore I cannot access my db.

I am sure somebody must have come across this before. The output below explains my situation:

Code:
metpmtc1:# metastat d501
d501: Soft Partition
    Component: d39
    State: Okay
    Size: 157286400 blocks
        Extent              Start Block              Block count
             0                    10177                157286400

d39: Concat/Stripe
    Size: 1286653440 blocks
    Stripe 0: (interlace: 128 blocks)
        Device     Start Block  Dbase State        Hot Spare
        c1t1d0s0          0     No    Okay         
        c1t2d0s0      10176     No    Okay         
        c1t3d0s0      10176     No    Okay         
        c1t4d0s0      10176     No    Okay         
        c2t1d0s0      10176     No    Okay         
        c2t2d0s0      10176     No    Okay         
        c2t3d0s0      10176     No    Okay         
        c2t4d0s0      10176     No    Okay         
        c2t5d0s0      10176     No    Okay

Code:
metpmtc1:# mount /dev/dsk/md/501 /spool 
mount: /dev/dsk/md/501 is already mounted, /spool is busy,
        or the allowable number of mount points has been exceeded
metpmtc1:# 
metpmtc1:# fstyp /dev/dsk/md/501
fstyp: cannot stat or open </dev/dsk/md/501>
metpmtc1:# 
metpmtc1:# fsck /dev/dsk/md/501
Can't stat /dev/dsk/md/501

Regards,
Duffs.

Hi,

Here it is however I have got the FS's commented out in the vfstab:

Code:

Use "/dev/md/dsk/d501" insted of "/dev/dsk/md/501" in all above commands.You are not writing "d" in the name of metadevice and writing wrong device path name.

Hi,

Thanks for noticing my typo but unfortunately it makes no difference:

Code:
metpmtc1:# mount /dev/dsk/md/d501 /spool
mount: /dev/dsk/md/d501 is already mounted, /spool is busy,
        or the allowable number of mount points has been exceeded
metpmtc1:# 
metpmtc1:# fstyp /dev/dsk/md/d501
fstyp: cannot stat or open </dev/dsk/md/d501>

R,
D.

Sorry, I edited my reply as I to made some typo mistake.
So, please check previous reply again.

And if still you get the error "/spool is busy" then just do following :

Code:
#rmdir /spool
#mkdir /spool

And then try to mount on it again...

Hi,

No joy:

Code:
metpmtc1:# rm -rf /spool
metpmtc1:# mkdir -p /spool
metpmtc1:# mount /dev/dsk/md/d501 /spool
mount: /dev/dsk/md/d501 or /spool, no such file or directory

I think it has got more to do with losing its pseudo path:

Code:
metpmtc1:# ls -l /dev/md/dsk/d502
lrwxrwxrwx   1 root     root          38 Apr 14  2005 /dev/md/dsk/d502 -> ../../../devices/pseudo/md@0:0,502,blk
metpmtc1:# ls -l /dev/md/dsk/d501
lrwxrwxrwx   1 root     other         38 Apr 30 17:55 /dev/md/dsk/d501 -> ../../../devices/pseudo/md@0:0,501,blk

D,
