Thanks for help. I've tried to mount with localalloc=16 before but that didn't solve the problem. Remounted with localalloc=4 and will monitor for system's performance.
As for disk space error - I'm not recieving this error if the target directory is local ext4 partition. That's why I assume that ocfs2 is the reason. My application resizes images dynamicly creating new sized pictures actually. However I receive out of space error not each time it tries to create new image - only sometimes randomly. 2015-07-17 3:50 GMT+06:00 Srinivas Eeda <srinivas.e...@oracle.com>: > then your application shouldn't get enospc error.
