Hello,
we are thinking about using BtrFS on standard hardware for a
fileserver with about 50T (100T raw) of storage (25×4TByte).
This is what I understood so far. Is this right?
· incremental send/receive works.
· There is no support for hotspares (spare disks that automatically
replaces faulty disk).
· BtrFS with RAID1 is fairly stable.
· RAID 5/6 spreads all data over all devices, leading to performance
problems on large diskarrays, and there is no option to limit the
numbers of disk per stripe so far.
Some questions:
· There where reports, that bcache with btrfs leads to corruption. Is
this still so?
· If a disk failes, does BtrFS rebalance automatically? (This would
give a a kind o hotspare behavior)
· Besides using bcache, are there any possibilities to boost
performance by adding (dedicated) cache-SSDs to a BtrFS?
· Are there any reports/papers/web-pages about BtrFS-systems this size
in use? Praises, complains, performance-reviews, whatever…
MfG
