Zitat von Charles Marcus CMarcus@media-brokers.com:
Hello,
I'm in the process of finalizing the spec for my new dovecot VM, and
this is the last question I need to address...I've read until I'm just about decided on XFS, but I have no
experience with it (been using reiserfs on my old box (@ 8 yrs old
now), and never had a problem (knock on wood), but considering its
current situation (little to no development support for reasons
everyone is aware of), I've decided now is the time to switch. It
came down to XFS or EXT4, and I like what I've read about XFS, but
am unsure how to tune it (or even if I should).I've decided to use mdbox for storage (been using maildir), and will
enable SIS for attachments.So, anyone (Stan?) have any suggestions? Should I go with EXT4? Or
XFS with just the defaults? Or XFS with one or more tuned parameters?Appreciate any suggestions (including links to docs dealing with
tuning XFS for my mail storage conditions that are written more at
the layman level) or comments from anyone experienced using both...
IMHO if you say "VM" than the filesystem inside the guest doesn't
matter that much. The difference of ext4/xfs are mostly the knowledge
and adjustability for special (high-end) hardware and the like. With a
Hypervisor providing some standard I/O channel and hiding/handling the
hardware details itself, most of the differences are gone. With this
in mind your question should maybe more of "what filesystem is more
Hypervisor friendly". For this i would suspect the simpler the better,
so i would choose ext4.
