Subject: Bug Report: Warning because of multipath ?
Date: Wed, 02 Mar 2011 20:49:05 +0000 [thread overview]
Message-ID: <1299098945.5103.198.camel@slave03> (raw)
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.
Regards,
