Is it a bad idea to add an additional drive to my zpool mirror while replaceing one of the drive in it?
All 4 drives are identical.
Is it a bad Idea to
zpool attach the new drive, and later
zpool detach the ones that do not behave?
Would adding another drive during resilvering add unneeded strain to already flaky disks?
(during resilver i remembered that i had replaced the “new” drive a few months ago since it was throwing errors, and never took it out of the machine. Oops)
