Subject: mixing raid1 and raid0?
Date: Sat, 25 Jul 2020 06:02:31 +0000 [thread overview]
Message-ID: <20200725055728.GA6238@dcvr> (raw)
Hey all, I've started using btrfs recently with old HDDs of
various sizes in a btrfs raid1 pool. It seems pretty good from
a flexibility and redundancy standpoint.
However, things like temporary files, caches, etc. don't need to
be raid1, and raid0 might allow me to reduce wear on HDDs; so
I'd like to make part of it raid0 while keeping most of it raid1.
If my btrfs is mounted as /mnt/btrfs, would the following do
what I want?
btrfs balance start -dconvert=raid1 -mconvert=raid1 /mnt/btrfs/precious
btrfs balance start -dconvert=raid0 -mconvert=raid0 /mnt/btrfs/junk
Or should I make a separate FS for temporary and disposable
raid0 data?
Thanks
