Andrew, We've been testing ZFS since about 10/24, see my original post (and replies) asking about its suitability "ZFS on Linux in production" on this list. So far, it's been rather impressive. Enabling compression better than halved the disk space utilization in a low/medium bandwidth (mainly archival) usage case. Dealing with many TB of data in a "real" environment is a very slow, conservative process; our ZFS implementation has, so far, been limited to a single redundant copy of a file system on a server that only backs up other servers. Our next big test is to try out ZFS filesystem send/receive in lieu of our current backup processes based on rsync. Rsync is a fabulous tool, but is beginning to show performance/scalability issues dealing with the many millions of files being backed up, and we're hoping that ZFS filesystem replication solves this. This stage of deployment is due to be in place by about 1/2014. -Ben On 11/30/2013 06:20 AM, Andrew Holway wrote: > Hey, > > http://zfsonlinux.org/epel.html > > If you have a little time and resource please install and report back > any problems you see. > > A filesystem or Volume sits within a zpool > a zpool is made up of vdevs > vdevs are made up of block devices. > > zpool is similar to LVM volume > vdev is similar to raid set > > devices can be files. > > Thanks, > > Andrew > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos >
