How could a drive fall out of a RAID? A RAID is nothing special, it's
just read/write commands given to a drive by a process called MD.
If the drive drops out of RAID it means it would have dropped out of
a normal computer doing normal I/O
Please explain
The RAID erroneously thinks that a drive has failed, and drops it from
the array.
Due to missing ERC/TLER and a bad sector, or another reason I am not
aware of?
And if it is "another reason", would you please explain how is that
different from what happens in a desktop? How come they are acceptable
for use in a desktop but they drop out of RAID? Why is RAID so special?
