Hey there. So, I created a ZFS pool, a RAID-Z with =E2=80=9Cda5 da2 =
da3=E2=80=9D. These are then the device names that appeared in =E2=80=9Cz=
pool status mypool=E2=80=9D. However, da3 had errors, and I replaced it =
by another disk living at da1. Then, I removed the bad disk and moved =
things in the enclosure. But, after this, some ids seem to have =
changed, and what was originally =E2=80=9Cda5=E2=80=9D is now =E2=80=9Cda4=
=E2=80=9D and =E2=80=9Czpool status mypool=E2=80=9D shows:
NAME STATE READ WRITE CKSUM
mypool ONLINE 0 0 0
raidz1-0 ONLINE 0 0 0
diskid/DISK-Z1Z946N90000R546NBZH ONLINE 0 0 0
da2 ONLINE 0 0 0
da1 ONLINE 0 0 0
If I use zdb, I can see that value stored in the =E2=80=9Cpath=E2=80=9D =
of each child of the vdev/pool. But, can I _change_ it? I know this is =
the reason many people suggest not using device names like I did, but, =
if I switch to gpt labels or the like, I=E2=80=98ll still need to update =
these in this existing vdev, right?
How can I change these path labels?
