I hear a lot of people swear that they have solid systems with xfs, and I am not saying that is not so, but here is some of my experience with it. Mind you this is a fairly large network cluster (webbot servers) and is growing constantly.. not a small home net.. your milage may vary. I have a client that I do a lot of work for who has a growing cluster of (currently more than 150) FC3 boxes (some early boxes were FC2 and have been moved to FC3).. AMD 3200-64's with 8 gb of ram per and running 6 drives per box - 1 TB SATA RAID arrays per box.. The cluster grows by about 6 boxes a week (this is my part). We started out running ext3 with lvm support as the filesystem because it is dependable and recovers very well from a crash and all was fine and rock solid.. Someplace along the line a few months ago one of his minions decided to dump the ext3 filesystem and started using xfs on the newer boxes being added and started changing the existing boxes over to xfs.. it has been a nightmare.. Lost data, corruption of the filesystem and a royal pain. The boxes run for a few weeks or more then start to puke the fs. After 2 months of trouble we are now migrating the entire site back to ext3. The slight speed increase over ext3 is not worth the cost of administration for them. The addition of more memory (from 4 to 8 gb) in each server has brought the overall performance of the ext3 boxes up to nearly the same performance levels that they were getting with the xfs filesystems due to the massive caching. In the 8 months I have worked for these guys, I have replaced about 21 drives out of more than 900 drives currently in use. It is NOT drive failure that has been the issue as the drives are all RAID. The boxes that so far have been moved back to ext3 are once again running just fine. I am just glad I am not the guy who decided that he had to change things as it was OK before messing with it all. Oh yeah... Aside from the occasional drive failure, the older ext3 boxes that were not converted are still running without errors. LOL As I said, your milage may vary.. we just are not getting the stability that others may see.. but again we are running under some very different conditions. One of my own primary servers is still running RH 9 ext3 and has an uptime of over 845 days as of this morning.
