Hi all,
I did my homework, and was browsing forums/internet for proper solution.
Seems, I could not find it.
Right now, I have rpool consisting from single SSD (250GB):
---8<------
:; pfexec fdisk /dev/rdsk/c2t0d0p0
Total disk size is 38934 cylinders
Cylinder size is 12544 (512 byte) blocks
Cylinders
Partition Status Type Start End Length %
========= ====== ============ ===== === ====== ===
1 Active Solaris2 1 28081 28081 72
2 Linux native 28081 29752 1672 4
3 Linux native 29753 38934 9182 24
---8<------
Partitions 2 and 3 are used for zfs caches (ZIL and ARC)
It was created long time ago, and zdb shows "ashift = 9" on it.
Now, I want to replace it with another SSD (500GB), with similar
partitioning (e.g. Solaris 2 partition for rpool, partitions 2 and 3 for
cache devices -- with adjusted values, of course) -- but with "ashift =
12" set.
What would be the best approach to achieve that (beside creating new
pool, and using zfs send/recv)?
Thanks in advance.
P.S: cache devices are used by another pool (located on HDD), to
speed-up its use
P.P.S: I apologize if I missed some (on the net) available documentation.
