Hi,
i got stuck while selecting the right FS for ceph / RBD.
XFS:
- deadlock / hung task under 3.0.34 in xfs_ilock / xfs_buf_lock while syncfs
- under 3.5-rc3 all my machines got loaded doing nothing than waiting
for XFS / SSDs so ceph is really slow / unuseable
btrfs:
- 3.5-rc3 ceph is pretty fast and works good until i see also a deadlock
while doing heavy random I/Os in my rbd / kvm.
All processes hang in btrfs_commit_transaction or
btrfs_commit_transaction_async
Are there tested / recommanded kernel versions for rbd and a specific fs.
