SubjectExt4 Kernel Crash
Dear Linux Kernel Developers,
I am writing to report a kernel or ext4 bug.
I have two servers populated with 2 LUNs from the main storage facility,
each server has one LUN which is about 1.2TB. On top of that I am
utilizing glusterfs and samba to mount the 2.4TB created space to a
Windows server and other Linux machines (via glusterfs native client).
Yesterday I tried to copy to the new storage glusterfs space about 788GB
and in the morning I got from both machines the attached kernel messages.
I have to mention that the first machine runs samba and mounts the
allocated glusterfs space with the help of FUSE glusterfs driver. The
second machine doesn't mount/export anything and simply runs the glusterfs
service.
I have to also add that similar problems have happened to another system
which is used as a TIF to JP2 converter. The conversion path starts from
the conversion of a pdf file to png and then to jp2. As you can imagine
this process produces hundreds of thousands of files. Similarly the
machine crashes and I get similar kernel messages concerning ext4. I can't
give you more information on that because the machine crashes, I have to
take a photo and send it back to you next time.
What do you believe about the kernel messages? Is this a ext4 bug when
thousands of files are created? How can I help resolve that?

Please Cc me because I am not in the list.

With kind regards,
Chris.


PS: Are there any ext4 kernel optimization's for avoiding that or
narrowing down the problem if this is not so obvious?
