Robert,
Which Solaris release is this?
Thanks,
Cindy

The fix for 6991788 would probably let the 40mb drive work, but it would
depend on the asize of the pool.

Hi Robert,
We integrated some fixes that allowed you to replace disks of equivalent
sizes, but 40 MB is probably beyond that window.
Yes, you can do #2 below and the pool size will be adjusted down to the
smaller size. Before you do this, I would check the sizes of both
spares.
If both spares are "equivalent" smaller sizes, you could use those to
build the replacement pool with the larger disks and then put the extra
larger disks on the shelf.
Thanks,
Cindy

In 2007 I bought 6 WD1600JS 160GB sata disks and used 4 to create a
raidz storage pool and then shelved the other two for spares. One of
the disks failed last night so I shut down the server and replaced it
with a spare. When I tried to zpool replace the disk I get:
zpool replace tank c10t0d0 cannot replace c10t0d0 with c10t0d0:
device is too small
The 4 original disk partition tables look like this:
Current partition table (original):
Total disk sectors available: 312560317 + 16384 (reserved sectors)
Part Tag Flag First Sector Size Last Sector
0 usr wm 34 149.04GB
312560350 1 unassigned wm 0
0 0 2 unassigned wm 0
0 0 3 unassigned wm 0
0 0 4 unassigned wm 0
0 0 5 unassigned wm 0
0 0 6 unassigned wm 0
0 0 8 reserved wm 312560351
8.00MB 312576734
Spare disk partition table looks like this:
Current partition table (original):
Total disk sectors available: 312483549 + 16384 (reserved sectors)
Part Tag Flag First Sector Size Last Sector
0 usr wm 34 149.00GB
312483582 1 unassigned wm 0
0 0 2 unassigned wm 0

0 0 6 unassigned wm 0
0 0 8 reserved wm 312483583
8.00MB 312499966
So it seems that two of the disks are slightly different models and
are about 40mb smaller then the original disks. I know I can just add
a larger disk but I would rather user the hardware I have if possible.
1) Is there anyway to replace the failed disk with one of the spares?
2) Can I recreate the zpool using 3 of the original disks and one of
the slightly smaller spares? Will zpool/zfs adjust its size to the
smaller disk?
3) If #2 is possible would I still be able to use the last still
shelved disk as a spare?
If #2 is possible I would probably recreate the zpool as raidz2
instead of the current raidz1.
Any info/comments would be greatly appreciated.
Robert
