Hi, We have ocfs2 1.4 and having high log file sync waits, which are mostly due to LGWR not able to complete writes fast enought for online redo logs. All of our online redo log file systems are created with default cluster size of 4K, If we get new file systems of cluster size 128 K or even of 1MB, will it help to speed up the writing to online redolog and reduce the i/o particular to this and help reduce log file sync waits? Indirectly we are looking to tune the heavy writes on the file system. which all properties of ocfs2 would help speed this up?
Appreciate the response from all of your's experience.. Regards, Pravin
