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?
