Perhaps some removable drives caused the change in drive names?
Regardless, I believe ZFS stores labels on each disk and is clever
enough to figure out what is what even if the operating system name
has changed.

If I recall correctly, a zpool export (if possible) followed by a
zpool import has always corrected this for me.

Barring an actual disk failure (which could have failed to enumerate
therefore throwing off naming) your data should be safe.
