Hello, I have installed a ceph firefly (0.80) on my system last year. I run a 3.14.43 kernel (I upgraded it recently from 3.14.4). ceph seems to be working well in most cases, though I haven't used it in real production mode as of now. The only thing I noticed recently was some Input/Output Error on a replicated block-device that I mounted successively on a node, then another when I stopped brutally the first one, then back on the first node, but I'm not asking for help on this problem now, as long as I don't know more about it (ceph is probably not to incrimnate). My question is : should I upgrade ceph ? do I take risks doing it ? what would be the benefits ? are there some behaviour changes that could cause problems ? I make minimal use of ceph : - 2 storage nodes only, with potentially several dozens of terabytes of disk, but probably not more than 32 GB of RAM - use of ceph block-device only, to create a replicated partition with almost all the disk space to make backups on it Thanks Pascal _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
