Subject: Why is converting from RAID1 to single in Btrfs an I/O-intensive operation?
Date: Sat, 18 Feb 2023 09:10:15 +0100 [thread overview]
Message-ID: <87wn4fiec8.fsf@physik.rwth-aachen.de> (raw)
Hallöchen!
I want to replace a device in a RAID1 and converted it temporarily
to “single”:
btrfs balance start -f -mconvert=single,soft -dconvert=single,soft /
This takes very long. I don’t see why, and wonder whether this is
the right approach in the first place. After all, no (significant)
amount of data should be needed to be transferred in the process,
should it?
A side question: Is -sconvert also necessary?
Regards,
Torsten.
