If we've found one bad disk, what are our options?
Live with it or replace it :-)

Similar question: a HDD went awry last week in an snv_117 box
(the controller no longer sees the drive - so I guess there is either
a dead drive, or dead power/data ports on the backplane), and
a hot-spare replaced it okay. However, there are a number of
CKSUM errors on the replacement disk, growing by about 100
daily (according to "zpool status"). I tried scrubbing the pool and
zeroing the counter with "zpool clear", but new CKSUM errors
are being found. There are zero READ or WRITE error counts,
though.
Should we be worried about replacing the ex-hotspare drive
ASAP as well?
There are no errors in dmesg regarding the ex-hotspare drive,
only those regarding the dead one, occasionally:
