Yep, ReiserFS has stood the test of time very well and I'm still using and abusing it still on various servers all the way from something like a decade ago! More recently I've been putting newer systems on ext4 mainly to take advantage of extents for large files on all disk types, and also deferred allocation to hopefully reduce wear on SSDs. Meanwhile, I've seen no need to change the ReiserFS on the existing systems, even for the multi-Terabyte backups. The near unlimited file linking is beautiful for creating in effect incremental backups spanning years! All on raid1 or raid5, and all remarkably robust. Enough waffle! :-) On 21/05/13 04:59, Duncan wrote: > And hopefully, now that btrfs raid5/6 is in, in a few cycles the N-way > mirrored code will make it as well I too am waiting for the "N-way mirrored code" for example to have 3 copies of data/metadata across 4 physical disks. When might that hit? Or is there a stable patch that can be added into kernel 3.8.13? Regards, Martin
