Hi all,
I understand, that a change from RAID5 to RAID6 by adding a single disk -
eg. keeping the number of data disks - requires a backup file throughout the
whole reshape process. For a larger, multi-TB array this means millions of
writes to the backup file, which - if i'm correct - means means millions of
writes to the same physical sectors of the disk that holds the backup file.
Is this not problematic? How many write operations can a typical drive
tolerate nowadays? (on the same sectors)
Lots, where Lots >= 1 and Lots < infinity.
I've never seen rotating media specify any form of limitation to writes.
Have you?
