(This is a duplicate post - I forgot to change the Subject!!)
Moving on from my previous post (metadisk and moving partition from
rawfs to ufs) I have found an issue where we upgraded two mirrored disks
from 18GB to 36GB some time ago.
What I didn't notice (kindly pointed out by Darren Dunham) was that the
Mirror has a different size to the Submirrors. i.e.
metastat d7...
d7: Mirror
Submirror 0: d17
State: Okay
Submirror 1: d27
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 11134456 blocks
d17: Submirror of d7
State: Okay
Size: 46137600 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c1t0d0s7 0 No Okay
d27: Submirror of d7
State: Okay
Size: 46137600 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
c1t1d0s7 0 No Okay
Anyone know ho I can fix this problem. This is definitely the issue I am
having with running out of space on this slice.
The odd thing is, df -k reports the slice as ~22GB but the d7 mirror
reports it as ~5.5GB
Any suggestions would be welcomed with open arms
Thanks
Andy

Hi everyone
I have recently moved a rawfs partition to a ufs partition to satisfy
upgrading of an application (InfoVista).
I have two disks that are mirrored where slice 7 is used for the
InfoVista databases. Slice 7 (/dev/md/dsk/d7) is now mounted
on /InfoVista.
The partitions are 22GB in size but I seem to be having problems writing
large amounts of data to them.
I have written a small perl file that writes a counter to a file
in /InfoVista/file but it doesn't get past line 9038.
I have a couple of questions
1. Is it possible to physically damage the disk while using md
2. How else can I prove that I have problems with this slice
Thanks
Andy
