This is the list about linux clustering, in a thread about linux cluster filesystems, after all :-) Previous poster described OCFS. You're talking about ocfs2. Two different things, right? The thread is about ocfs2. The poster may have been talking about ocfs, but I wanted to clarify because either 1) he meant 'ocfs2' and I want to understand what isn't POSIX, or 2) he meant 'ocfs' and he may confuse people who are reading for info about ocfs2. Yeah, I might have jumped in too quickly. But, if someone writes OCFS, I generally understand it to mean not ocfs2. It was annoying to us for a while as we have both running separately and it caused quite a bit of confusion for all the different people having to interact with both.

Re: [Linux-cluster] SCSI Reservations Red Hat Cluster Suite
Nice overview. Wish I had this a few weeks ago :-) I am curious as to why LVM2 is required? With simple modification of the scsi_reserve (and maybe fence_scsi), using an msdos partitioned disk seems to work fine. This is only in testing but I haven't seen any issues as of yet.

Re: [Linux-cluster] SCSI Reservations Red Hat Cluster Suite
True. Any solution for auto discovery? I've no problem with statically defining a device, but that would be pretty nice if possible. Alex Kompel wrote: On Fri, Mar 28, 2008 at 8:15 AM, Ryan O'Hara [EMAIL PROTECTED] wrote: The reason for the cluster LVM2 requirement is for device discovery. The scripts use LVM commands to find cluster volumes and then gets a list of devices that make up those volumes. Consider the alternative -- users would have to manually define a list of devices that need registrations/reservations. This would have to be defined on each node. What make this even more problematic is that each node may have different device names for shared storage devices (ie. what may be /deb/sdb on one node may be /deb/sdc on another). Furthermore, those device names could change between reboots. The general solution is to query clvmd for a list of cluster volumes and get a list of devices for those volumes. You can also use symbolic links under /dev/disk/by-id/ which are persistent across nodes/reboots. -Alex -- Linux-cluster mailing list Linux-cluster@redhat.com https://www.redhat.com/mailman/listinfo/linux-cluster ___ Inbound Email has been scanned by Nexa Technologies Email Security Systems. ___ -- Jeff Macfarland ([EMAIL PROTECTED]) Nexa Technologies - 972.747.8879 Systems Administrator GPG Key ID: 0x5F1CA61B GPG Key Server: hkp://wwwkeys.pgp.net -- Linux-cluster mailing list Linux-cluster@redhat.com https://www.redhat.com/mailman/listinfo/linux-cluster
