Hi OCFS Gurus... I have 2 questions for OCFS ver 1.0.10.1 1. What is the Maximum mount point suggested if we are using OCFS ? 2. Is there any method to tune the OCFS to booster the IO performance? Awaiting ur responses... Thanks in Advance... Rgds/Jeram

Hi All, we are using Red Hat 2.1 Kernel e38 along with MSA 1000. ocfs version being used is $ rpm -qa | grep ocfs ocfs-tools-1.0.10-1 ocfs-2.4.9-e-enterprise-1.0.12-1 ocfs-support-1.0.10-1 Database Version is 9.2.0.5 However we find that the performance of the database on OCFS is too slow. even a select count(1) from all_tables takes like a while to complete. We initially assumed RAC is

Dear all... Currently I am having 5 RAC nodes with Configurations as below : 1. HW = DL580 32 Bit Processor 2. OS = RHAS 2.1 3. OCFS= Latest Version 4. RAC= Oracle9i 9.2.0.5 (32 Bit) Now I am planning to add 2 more Rac Nodes in the existing RAC: 1. HW=Itanium 64 bit processor 2. OS=RHAS 3.0 3. OCFS=Latest Version 4. RAC=Oracle9i 9.2.0.5 (32 bit) Can I

(Yep, it's me again) We've worked around some minor glitches and now have a pair of nodes happily sharing an OCFS volume. I was wondering, though, if it was possible to configure a second private IP address so that the nodes could communicate over more than one Gigabit Ethernet connection. Our RAC books and online docs make some vague references to multiple interconnects, but I have yet

Hi, well i mounted the OCFS drive over nfs, but it seems to have problems with it, because the NFS does not detect changes (if I add or delete files) the nfs shares still shows the old status. If i delete a file on the OCFS volume, and i am doing a "ls" on one of the nfs clients, it says for every file which was on the ocfs, "no such file or directory". Did I miss

A few weeks back we opened a TAR with Oracle support to determine whether an OCFS (1.0.9-12) + async configuration was considered supportable. At first a technician said yes, but I followed up with Wim's explanation of how that combination is potentially troublesome and inadequately tested. The technician double-checked, then confirmed that OCFS + async is considered risky. He did say that a

So is there any possibility of getting it so that the Subversion repository can get the check-in comments from the internal CVS repository? At the moment every log file comment I see in SVN is "Sync". Which doesn't really let me know what has happenned without having to go lock at the actual diff between the two versions. And even then I may not have any idea why the change was

Hi all... I have a strange problem. 2 of my mount points already use 7% of space, even when I check the directory is empty. When I re-format it, it release the space for a while, after 1 or 2 days, the space is used again for 7% - 10 %. What could be the reason? I am using RHAS 2.1 Enterprise Kernel 2.1 and OCFS release 1.0.9-6 Thanks Jeram

Hello again. I am setting up a new pair of servers to run RAC. They're connected via fibre-channel to a hardware RAID array, and both are able to see the exposed LUNs. When I create an OCFS filesystem on one node with mkfs.ocfs, I can mount it. When I try to mount from the other node, however, it fails. After that, the filesystem is left in a state where neither node can mount it. The
