I=E2=80=99m moving one of my systems from the on-board SATA controller =
to a SATA/SAS controller. A side effect of the first experiement, of =
moving half of the SATA drives onto the new controller, is that they =
went from being named =E2=80=9Cada2=E2=80=9D and =E2=80=9Cada3=E2=80=9D =
to being =E2=80=9Cda0=E2=80=9D and =E2=80=9Cda1=E2=80=9D.
ZFS, happily, just coped with this. But, the raidz1 pool that was =
spread across parts of disks on both sides, now looks like:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
raidz1-0 ONLINE 0 0 0
ada1p4 ONLINE 0 0 0
diskid/DISK-WOL240261932p1 ONLINE 0 0 0
diskid/DISK-WOL240261922p1 ONLINE 0 0 0
(where before, the second and third components were ada2p1 and ada3p1).
1) Is it possible to rename how zpool lists these disk identifiers?
2) If so, is there consensus on whether device names or diskid are =
=E2=80=9Cbetter=E2=80=9D, perhaps simply =E2=80=9Cmore recommended"? In =
a way, I=E2=80=99d like an idea how to tell which disk in the enclosure =
is which device in the pool, which I think diskid would make harder=E2=80=A6=
Thanks.
