When I used reiserfs, I suffered a lot of file corruption on unclean shutdowns. I.e., every time there was a power failure, or my computer wedged for some reason, my Gnome config files would become corrupt and I'd have to reconfigure Gnome from scratch. I don't know if this problem is still the case with more recent versions of reiserfs (I think it is because worrying about file corruption was apparently not one of the design goals of reiserfs), but this design tradeoff was apparently known to be "feature" of reiserfs at the time. Since then, I'd be rather wary of using reiserfs on anything other than a filesystem used solely for Netnews or MH, which seems to be its target application domain. (I.e., lots and lots of small files.) I can probably cope with a few corrupted mail files, but even that would be a bit annoying, if an important mail file were trashed. After switching back to ext3fs, however, I noticed no performance problems with huge MH directories containing 100,000+ files, so I think I'd stick with ext3fs for even MH. Maybe I'd use reiserfs for News. [Tangentially related factette: I can't use HFS on OS X with MH because the performance is terrible when mail folders get too large. MH using folders on a UFS filesystem on OS X, though, performs fine.] > The flaw I see in doing this is that I believe I either need tape > backup or another equivalent setup (physical second RAID5) to rsync to > to prevent bit corruption (not hardware failure.) I've had two drives die at the same time on a RAID. Good thing the RAID was only used as our backup server. I'd never trust RAID again to be any kind of security against disk failure. |>oug _______________________________________________ bblisa mailing list [email protected] http://www.bblisa.org/mailman/listinfo/bblisa
