At home I started playing about two years ago. I am now using a 3 disk raidz and a mirror. Had big problems with my hardware at the beginning. But thanks to ZFS I was able to eliminate the bad disks. Now everything is working. At work I have one server running for 2 months now without big troubles ~30 linux $HOME volumes on a SSD mirror ~350 RO and 250 RW volumes on 12x2TB sata mirror +l2arc > * If not, and you looked into it, what stopped you? > * If you are, how is it working out for you? I set arc_max to 8GB on a 24GB machine which lets me 1.9GB free at the moment. There have been suggestions on the mailinglist to play with arc_metadata_max and to set vm.min_free_kbytes to about 1% of RAM to avoid huge load or a lock up. I have not played around with this because limiting arc to 8GB es good enough for me at the moment. With compression set to lz4 it gives me good performance. I strongly suggest to test well and to have a look at the current limitations of zfsonlinux (there have been several discussions on the mailing list). regards Markus -- Markus Koeberl Graz University of Technology Signal Processing and Speech Communication Laboratory E-mail: [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
