...Our Oracle support rep pointed us to Metalink note #1232702.1 and suggested we should script something up to periodically check the free contiguous blocks in the group chains for the volume in question. Reading the note, I get how to get Clusters per Group X Bits per Cluster from the "stat //extent_alloc:NNNN". What I'm confused about is parsing the "stat //global_bitmap" section, and I thought I might have a better chance of getting an explanation from the audience here. I have 2 basic questions: 1) The note above says that a "highly fragmented volume will have many&quot...

Another simple question. How do I calculate the size of the volume from the superblock? Do I just use the two fields: u_int32_t s_blocksize_bits; /* Blocksize for this fs */ u_int32_t s_clustersize_bits; /* Clustersize for this fs */ What is the formula to use? Thanks, John

Recently I ran into a situation where an ocfs2 (1.4) volume was reporting it was out of space when it was not. Deleting some files helped short term but the problem quickly comes back. I believe this is due to the fragmentation bug that I have seen references to in the mailing list archive. I am trying to reproduce the problem on a test system so that I can validate that upgrading to 1.6

Hi all. I have a 50 GB OCFS2 file system. I'm currently using ~26GB of space but df is reporting 43 GB used. Any ideas how to find out where the missing 17GB is at? The file system was formatted with a 16K cluster & 4K block size. Thanks, Matt -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi All, We have encountered a case that extent alloc gd has been abnormally cleared. In our environment, the volume has been formatted with 128 slots but actually has 64 slots in use. Since extent alloc is allocated when formatting, and extent_alloc:0107 (inode 259) hasn't been use in our environment, I have no idea how it can happen. Does any one have an idea?

Hello. I'm having issues using ocfs2 and drbd in dual primary mode. After running some filesystem test's that create a lot of small files I run really fast into "No space left on device" The non failing node is able to write/read from the filesystem. And the failing node is also able to delete/read from the filesystem Ubuntu custom kernel 2.6.27.2 o2cb_ctl version 1.3.9 drbd

Hello, We have a 3-node cluster setup with ocfs2. Since friday one of the nodes went down and would not become clustermember after a reboot because it was unable to write to the ocfs2 filesystem. Message: no space left on device. There is plenty of diskspace though. No problem whatsoever to create a file / directory on the filesystem using one of the other nodes. Today one of the remaining

Hi, we have recently started to use ocfs2 on some RHEL 5.5 servers (ocfs2-1.4.7) Some days ago, two servers sharing an ocfs2 filesystem, and with quite virtual services, stalled, in what it seems on ocfs2 issue. This are the lines in their messages files: =====node heraclito (0)======================================== /Dec 4 09:15:06 heraclito kernel: o2net: connection to node parmenides

Hi, I'm sending a series of patches implementing quota support into ocfs2-tools. It's the same as the original huge patch I've sent but now it's split as Joel asked. I've also realized that when disabling SPARSE feature, we should update quota information. That piece of code is missing, I'll implement it soon. Comments welcome. Honza

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

Hi, below comes a new version of the series of patches implementing quota support for ocfs2-tools. I've fixed the calls of ocfs2_malloc_blocks() which were given number of bytes instead of number of blocks. Besides that the series should be the same. Honza
