similar to: mounting a snapshot for backup.

We have a test 10gR2 RAC cluster using ocfs2 filesystems for the Clusterware files and the Database files. We need to increase the node slots to accomodate new RAC nodes. Is it true that we will need to umount these filesystems for the upgrade (i.e. Database and Clusterware also)? We are planning to use the following command format to perform the node slot increase: # tunefs.ocfs2 ?N 3

I need add extra 2 nodes into current 3 nodes ocfs2 file system which means 5 nodes share this file system after it. I think this file system creates by mkfs.ocfs2 -b .. -N 4 .. which only allows 4 nodes. Questions: 1. How to verify parameter when this file system created? In this case, it is 4 nodes. 2. I assume I have to recreate the files system which will lost contains, if I use

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

I am working currently on cloning on a regular basis our production OCFS2 volumes to our test environment. For the database (Oracle 10G R2 RAC) we put it into backup mode, then execute a Snapclone on our 3Par SAN. Then we use RemoteCopy and SnapClone to our development 3Par SAN. To recover the OCFS2 volume I got through the following steps: Stop database umount /export/<volume name> Log

Hi all, I upgraded ocfs from 1.2 to 1.4 after the update I launched tunefs.ocfs2 to enable the new ocfs2 features (sparse files and unwritten extents). tunefs.ocfs2 is now running since 2 days (12T partition) and I need my system back to production, can I safety abort tunefs.ocfs2? thanks Nicola

Hi, I am little puzzled. I looked through the mailing list archive and some other sources but doesn't seem like anything anyone encountered. I have two systems with attached HP SAN. I'm using SLES 10.1 with multipath-tools. When trying to mount OCFS2 device I get this: SERVER:/ # mount.ocfs2 /dev/mapper/mpath0 /mnt/temp/ mount.ocfs2: Invalid argument while mounting

One of ocfs2 filesystem has some errors. 1. fsck.ocfs2 informs me that : "I/O error on channel while reading .. " It was NOT TRUE - I was able to read and write entire storage over the network multiple times. 2. becouse of CRC errors and suggestion to disable metaecc I run tunefs.ocfs2 --fs-features=nometaecc /dev/xxx funefs allocate 9,89 GB of virtual memory and 95% of

Just checking to be sure this isn''t a known bug or problem. I couldn''t find a bz for this, but it would appear that tunefs.lustre --print fails on a lustre mdt or ost device if mounted with mmp. Is this expected behavior? TIA mds1-gps:~ # tunefs.lustre --print /dev/mapper/mdt1 checking for existing Lustre data: not found tunefs.lustre FATAL: Device /dev/mapper/mdt1 has not

Hi, I'm sending a patch for proper quota support when disabling sparse feature. The second patch fixes a minor problem in tunefs.ocfs2 when disabling the sparse feature. In a few days I plan to resend the whole "quota support" series with all the changes people request included... Honza

RHEL 4 (CENT OS) Am I waisting my time trying to get the 10G Clusterware installer to use OCFS2 volumes for the voting and OCR disks ? The ocfs2 setup seems happy on both nodes but the 10G installer says the location entered for the oracle cluster registry (OCR) is not shared across all the nodes in the cluster Do the volumes need to mounted ? I did with no change . [root@green rc5.d]#

I am trying to make a mysql standby setup with 2 machines, one primary and one hot standby, which both share disk for the data directory. I used tunefs.ocfs2 to change the number of open slots to 1 since only one machine should be accessing it at a time. This way it is fairly safe to assume one shouldn't clobber the other's data. Only problem is, if one node dies, the mount lock still

Hi List, i'd like to share with you what happened yesterday. Kernel 2.6.36.1 ocfs2-tools 1.6.3 (latest). I had an old OCFS2 partition created with a 2.6.32 kernel and ocfs2 tools 1.4.5. I unmounted all partitions on all nodes in order to enable discontig-bg. I then used tunefs to add discontig-bg, inline-data and indexed-dirs. During indexed-dirs tunefs segfaulted and since then, fsck

Add online resize in tunefs.ocfs2 so that user can increase the volume when it is mounted.

Hi, I have installed and configured ocfs2 as per the given guidelines on two nodes. The output of the service status of o2cb and ocfs2 is as under: Node: rashida1 -------------------------------------------------- [root at rashida1 ~]# service o2cb status Driver for "configfs": Loaded Filesystem "configfs": Mounted Driver for "ocfs2_dlmfs": Loaded Filesystem

Greetings, I read from archive that OCFS is for kernel 2.6. which means RHAS4.0 is supported. However, I can't find the download for this version. Is the support official and where can I download it.

Hi, this is the next version of quota support for quota tools. I've addressed all the comments of Tao, Joel and others. Sparse feature disabling also correctly updates quota information now and the patch is merged into the tunefs support patch. Honza

Good morning, I'm trying to build ocfs2-1.4.7 against a Centos 5.3 distro with a 2.6.30 kernel.
