Title:
kernel BUG at fs/ocfs2/alloc.c:1514
Status in linux package in Ubuntu:
Incomplete
Bug description:
The current bionic kernel (4.15) contains a known bug in the OCFS2
distributed filesystem, which can cause all nodes (!) of a redundant
cluster to crash. More information on this bug (including the patch)
can be found here: https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=841144
This fix was included upstream in 4.16, so it is included in the HWE
stack, but not in the GA kernel.
In my opinion this is quite severe bug, because it can bring a whole
redundant setup down (this happened to us). This patch should be
backported to 4.15.
#cat /proc/version_signature
Ubuntu 4.15.0-45.48-generic 4.15.18
