Solaris

Hi, i encounter problem during middle progress of mirroring. i trying create a mirror (metainit) to my slice 7. Who's have any experience, can you please help me?

i tried create a state database replica "metadb -afc1 /dev/dsk/cxtxdxs7" but at it show it cannot create caused /dev/dsk/cxtxdxs7 had mounted so I unmount the slice 7 (cxtxdxs7).

therefore, i unmount it "umount /metadb1" and i able create state database in slice 7. but a problem emerge that i cannot mount it back.

Code:

#metadb
flags                first blk              block count            
a  m  pc   luo     16                    8192                    /dev/dsk/c1t0d0s7
a      pc   luo     16                    8192                    /dev/dsk/c1t1d0s7
a      pc   luo     16                    8192                    /dev/dsk/c1t2d0s7
a      pc   luo     16                    8192                    /dev/dsk/c1t3d0s7

This is the error msg.
error message

NOTICE: mount: not a UFS magic number (0x0)
mount: /dev/dsk/cxtxdxsx is not this fstype


i saw it's tag in slice 7 is unassigned, is it cause the error? or who's talk to me what's getting wrong?

The metadb is just a raw slice that is used by the lvm software. It's not supposed to be mountable. We frequently use slice 7 for the metadb. But then slice 7 should be small, just a few cylinders. You should also create another metadb on slice 7 of your other disk. Then you just leave them alone and let the lvm software manage them. Yes, the data is replicated between the two slice 7's, but this is not usually called a mirror.

oh, this is for testing only so it is not matter for cylinders size.

I had create the mirror and submirror last weekend. 2 submirror refer to both slice 7 in different disk. but I still cannot mount back the slice 7. It also had problem when i boot-up server, typically it is go the GRUB login interface.

This is login interface warning.
