Hello Ladies and Gents .. First time poster .. I have been experiencing several issues with unexplained Fencing and silly mount/unmount errors With Version 1.4.7 on UEK (Red Hat Enterprise Linux Server release 5.3) running under kernel 2.6.18-128.el5 With ocfs2console-1.6.3-2.el5,ocfs2-tools-1.6.3-2.el5 & ocfs2-2.6.18-128.el5-1.4.7-1.el5 RPM Packages. You See, the problem is that I was going to deploy OCFS2 in about 32 nodes for general purpose "file/Middle Tier Application/RMAN Backup repository" sharing (since NFS is too slow, and GFS only supports 16 nodes) When doing a web search for ocfs2 production ready I ran across this page http://geekscrap.com/2010/01/what-evil-lurks-in-ocfs2/ and it scared the living daylight out of me. / (Not enough disk space,quorum needing manual restore,several racing conditions in file locking that lead to corruption,fsck taking forver after having to run it manually, in some cases leading to corruption and dead unrecoverable FileSystems ) / So I have some questions: 1.- Are some/all of these issues resolved ?, 2.- If your Job depended on it would you use OCFS2 Now , using the same version/release 3.- Can we expect to see Release 1.6 without these bugs to be available @ http://oss.oracle.com/projects/ocfs2/files/RedHat/RHEL5/x86_64/ Soon. 4.- if 1.6 Is available in RPM form, stable and downloadable .. Where is it ? So the bottom line question is .. Should I look at alternative Cluster FileSystems or should I take the plunge once 1.6 is made available without these major bugs ? (or even now with Rel 1.4.7-1) ?? Cheers. Flames welcome ;) Thanks. -- Adrian Salaices Sr. Linux Administrator Tomkins Building Products 972-943-6104 Tel 1301 W. President George Bush Hwy.

Hello Mr. Salaices,> 1.- Are some/all of these issues resolved ?,Some of them are solved in 1.6 and some are bogus, like the issue 4 -- the OCFS2 does not officially support SAMBA shares, so reporting problems with it is pointless.> 2.- If your Job depended on it would you use OCFS2 Now , using the > same version/releaseMy Job depends on it and we have two clusters deployed in production and are planning the third. They are small, but with heavy IO load, mainly e-mail. Cluster 1 (running since 01/2008): OCFS2 1.4.4 two nodes SuSE Enterprise 10SP3 Storage: Dell/EMC AX-100 - fibre channel - 800 GiB volume Will be upgraded to CentOS 5.5 with OCFS 1.6.3 Cluster 2 (running since 11/2010): OCFS2 1.6.3 two node (two more underway) CentOS 5.5 + Unbreakable Kernel Storage: Dell EqualLogic VX4000 - iSCSI - 3.6 TiB volume Cluster 3 (planned): OCFS2 1.6.x four node CentOS 5.5 + Unbreakable Kernel Storage: Unknown - iSCSI - unknown size> 3.- Can we expect to see Release 1.6 without these bugs to be > available @ > http://oss.oracle.com/projects/ocfs2/files/RedHat/RHEL5/x86_64/ Soon.OCFS2 1.6 fixes a lot of bugs, including the "filesystem full" problem. Take a look at the user guide: http://oss.oracle.com/projects/ocfs2/dist/documentation/v1.6/ocfs2-1_6-usersguide.pdf> 4.- if 1.6 Is available in RPM form, stable and downloadable .. Where > is it ?Yes, it is. You can download it from the public yum repository: http://public-yum.oracle.com/ but I can't tell for sure if it works on RHEL 5.3, because the kernel is available for RHEL/OL/CentOS 5.5, 5.6 and 6.0.
