Subject: Number of parity disks
Date: Sat, 5 Mar 2022 15:09:55 +0900 [thread overview]
Message-ID: <p06001087de48ad4092ee@kyoto-arc.or.jp> (raw)

Hi Folks
I use mdadm conveniently.
Let me ask a very very basic question.
One parity disk can be used in RAID 5 and 2 parity disks can be used in RAID 6.
ZFS RAIDZ-3 (raidz3) can use 3 parity disks.
Is it difficult to increase the number of parity disks to 4, 5 or more.
If so, is the reason for this because of the time it takes to
generate the parity bits?
