Hi,
is there anything that speaks against putting a cyrus mail spool onto a
btrfs subvolume?
I might be the lone voice on this, but I refuse to use btrfs for
anything, much less a mail spool. I used it in production on DB and Web
servers and fought corruption issues and scrubs hanging the system more
times than I can count. (This was within the last 24 months.) I was
told by certain mailing lists, that btrfs isn't considered production
level. So, I scrapped the lot, went to xfs and haven't had a problem
since.
I'm not sure why you'd want your mail spool on a filesystem and seems to
hate being hammered with reads/writes. Personally, on all my mail
spools, I use XFS or EXT4. OUr servers here handle 600million messages
a month without trouble on those filesystems.
Just my $0.02.
