Hi, I use a cluster of 4 nodes with ocfs2 as a webserver cluster. During a stresstest it occurs after a couple of minutes that the webserverprocesses are ideling but the system load is extremely high (abou 150...200) where the waits are very low. After that I cannot interrupt the webserver processes anymore and in some directories a "ls -ls" comes not back - so it seems that the file system has a problem. Only a reset of the server solves the problem ;-((
In the debug mode I can find the following lines as an example: Lockres: D00000000000000000ccda0fcc1c07e Mode: Exclusive Flags: Initialized Attached RO Holders: 0 EX Holders: 0 Pending Action: None Pending Unlock Action: None Requested Mode: Exclusive Blocking Mode: Invalid Lockres: M00000000000000000ccda0fcc1c07e Mode: Exclusive Flags: Initialized Attached RO Holders: 0 EX Holders: 0 Pending Action: None Pending Unlock Action: None Requested Mode: Exclusive Blocking Mode: Invalid Lockres: D00000000000000000ccd9ffcc1c07d Mode: Exclusive Flags: Initialized Attached RO Holders: 0 EX Holders: 0 Pending Action: None Pending Unlock Action: None Requested Mode: Exclusive Blocking Mode: Invalid Lockres: M00000000000000000ccd9ffcc1c07d Mode: Exclusive Flags: Initialized Attached RO Holders: 0 EX Holders: 0 Pending Action: None Pending Unlock Action: None Requested Mode: Exclusive Blocking Mode: Invalid Could it be that two servers like to write to the same file and under heavy load the clusterd processes cannot handle this?
