Subject: btrfs bug reports?
Date: Thu, 14 Mar 2013 23:47:19 -0400 [thread overview]
Message-ID: <514299C7.4060200@lolwut.org> (raw)
Hi,
Is the linux-btrfs list interested in receiving bug reports relating to
btrfs?
If so, the following error occurred on a server of mine when copying a
large amount of data to a linear md-RAID formatted as btrfs. The data
transfer hung, and any attempt to kill or strace the copy process hung
as well until the system was rebooted.
