We use EMC's BCV for OCFS2 split mirror and it works just fine (10.2.0.3 and RH Linux 4). The only problem is we can't backup to tape directly from ocfs2 (we are using legato and I haven't heard of any other third party s/w doing this without rman). So, we copy files to ext3, zip them and then take tape backup.

Using Linux LVM and OCFS2, does anybody knows if is possible to dinamically extend an OCFS filesystem, once the underlying LVM Volume has been extended ?

You should use data pump or exp utilities to backup your database. To extend your fs, tune2fs.ocfs2 requires you to umount it, according to it's man page: == tunefs.ocfs2 is used to adjust OCFS2 file system parameters on disk. In order to prevent data loss, tunefs.ocfs2 will not perform any action on the specified device if it is mounted on any node in the cluster. This tool requires the O2CB cluster to be online. == The concrete command should be: tune2fs.ocfs2 -S /dev/LVM_volume I don't know if there's any way to extend it without umounting it. If you want to extend your fs without umounting it you should use ASM instead of OCFS2. regards, Jordi Riccardo Paganini wrote: > Does anybody knows if is there a certified procedure in to backup a RAC > DB 10.2.0.3 based on OCFS2 , > via split mirror or snaphots technology ? > > > Using Linux LVM and OCFS2, does anybody knows if is possible to > dinamically extend an OCFS filesystem, > once the underlying LVM Volume has been extended ? > > Thanks in advance > Riccardo Paganini > > _______________________________________________ > Ocfs2-users mailing list > [email protected] > http://oss.oracle.com/mailman/listinfo/ocfs2-users > > ------------------------------ Message: 3 Date: Mon, 8 Oct 2007 11:49:29 -0700 From: "Alexei_Roudnev" <[EMAIL PROTECTED]> Subject: Re: [Ocfs2-users] OCF2 and LVM To: "Jordi Prats" <[EMAIL PROTECTED]>, "Riccardo Paganini" <[EMAIL PROTECTED]> Cc: [email protected] Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=response I dont knoiw any lvm technology which can make a snapshort in clustered environment, so better forget this idea. Recommended method to do oracle backups is rman. Any violation of this brings you into the swamp of possible oracle bugs. ----- Original Message ----- From: "Jordi Prats" <[EMAIL PROTECTED]> To: "Riccardo Paganini" <[EMAIL PROTECTED]> Cc: <[email protected]> Sent: Monday, October 08, 2007 11:20 AM Subject: Re: [Ocfs2-users] OCF2 and LVM > Hi, > I'm not an expert on oracle, but I don't think using a snapshot is a > recommended backup solution.
