Hi, new to all of this OCFS2 stuff...planning on using it for a production 10gR2, EBS 11.5.10.2 RH 4 system...4 nodes sharing disks...all connected to an EMC storage array. Each node is a 2xXeon 3GHz(+) (with HT = 4) CPU box, with 8 G RAM.
Looking at using OCFS2 for Shared OH, Shared APPL_TOP, and Datafiles etc. Doing some very basic perfoamnce testing as I found OCFS2 very slow when applying 11.5.10.2 Maintnance Patch. On 'normal' etx3 file systems - copying 18G (APPL_TOP - 100,000 files) from one file system to another took 15 minutes. On another box - with NOTHING else running...copying same filesystem structure from one OCFS2 filesystem to another OCFS2 filesystem took > 1.5 hours - I killed it eventually. kswapd was going mad - consuming LOTS of CPU - top of 'top' majority of the time when copying in progress. Tried reformating the 'target' file system with 64K cluster size - block size was/is 4K...again same result - slow copying of files, kswapd going mad... I'm I missing something - or is OCFS2 not supposed to be a 'general purpose' clustered file system? I know it supposed to be certified for shared OH ? Project Manager is getting scared - not happy with performance - say OCFS2 is not ready for the prime time...? wants to start using GFS from RH...but costs a small fortune...not sure we can justify the cost...
