Just want to let everyone know that with a couple of all-nighters I was able
to replace my NFS mounted home directories with GlusterFS replicated across
two servers.
A couple of things I learned:
Server side AFR doesn't work right. Not sure if I really care. It would have
been nice to use the bonded Gigabit connection between the servers to do the
mirroring, rather then client/server network bandwidth, but... oh well.
Some apps have issues with direct-io on the client side. The most notorious
one I had problems with was KMail. Disconnected IMAP indexes would be written
to, then not read, causing peoples email to seemingly disappear. It took me
HOURS to figure that out. Another one was Firefox and it's sqlite databases.
Although I haven't tested it, I'm sure Akonadi and it's mysql
databases would
have an issue as well.
Anyway, I hope this info saves others some time.
