Hi everyone, I've the following configuration: Distro: Gentoo Kernel: vanilla 2.6.38-rc6 AMD64 Details: I use btrfs on a Dell MD3000i iSCSI disk. I'm connected with 2 ethernet cards with multipath to one raid controller. The mounted partition is also accessed from other servers via nfs.
The mount options are: "rw,compress,thread_pool=15,compress-force" I think that this error happens when the network is under heavy load and also the btrfs is having multiple i/o.
