Hello,
I've been fiddling with GlusterFS 3.3 to try and improve performance.
It seems something funny has happened in my hacking. Now I am seeing
many file access errors like:
rsync: read errors mapping "/global/...": No data available (61)
An ls -lR shows the files to be there ...
Having similar issues trying to open the files in other programs. This
doesn't happen all the time, but it is ~ 50% and sort of randomly. But
when it starts to happen, say in an rsync over a whole directory, then
it continues for each subsequent file.
I also see many errors like
1-global-io-cache: page error
in /var/log/gluster.log
Any ideas?
I've tried stopping and bringing gluster back up and remounting. I've
found the physical location of a few files on the servers and
successfully read them, also rsync'd them locally to /tmp. I am at my
wits end here ... up to now GlusterFS was running without a hitch for ~
1 year.
thanks!!
