just throw it out of the array - on a RAID 1 with two disk you have
still redundancy and i won't trust a disk which recognized that it has
errors on it's own
Why ? if it's just a single sector, the rest of the disk could be used
properly until the replacement.
i simply don't trust drives which have thrown errors
you don't lose anything when you push it out of the array
what's the point of "can i delay" when you have no other options? :-)
The option is: i've ordered the new disk, it should arrive this thursday.
If i'm still on the safe side, i'll wait, if not, i'll replace with
the first disk I have here, even if slower
you are clearly on the safe side with 3 mirrors and every rebuild wears
out the remaining drives, 1 out of the 3 would be enough since they hold
identical data
----------------------
the only thing one should think of: are all 3 drives identical types
with identical age - then it's more likely that they fail all within a
short time
that's why i try to mix different disks in a mirror to avoid failing
both sides of a mirror due firmware-error or a charge of bad disks
----------------------
as i replaced my HDD to SSD i removed two drives out of my RAID10, as it
didn't boot exchange two of them
so at that point 1 mirror of each stripe was a HDD and one a new SSD,
after one year i replaced the remaining two disks
2 x 850 EVO 2TB
2 x 860 EVO 2TB
/dev/sda: GB Written: 72.020
/dev/sdb: GB Written: 69.709
/dev/sdc: GB Written: 91.367
/dev/sdd: GB Written: 94.134
pretty impossible that both sides of the same mirror will fail within a
few hours
