[PATCH] the ac->ac_allow_chain_relink=0 won't disable group relink
...;t keep the credits for all chain relink,but ocfs2_claim_suballoc_bits overrides this in this call trace: ocfs2_block_group_claim_bits()->ocfs2_claim_clusters()-> __ocfs2_claim_clusters()->ocfs2_claim_suballoc_bits() ocfs2_claim_suballoc_bits set ac->ac_allow_chain_relink = 1; then call ocfs2_search_chain() one time and disable it again, and then we run out of credits. Fix is to allow relink by default and disable it in ocfs2_block_group_alloc_discontig.

AW: ocfs2_search_chain: Group Descriptor has bad signature
...1 ? Although they were not directly involved in corruption, maybe indirect ? Thanks, Vladan -----Urspr?ngliche Nachricht----- Von: Sunil Mushran [mailto:Sunil.Mushran@oracle.com] Gesendet: Dienstag, 1. August 2006 04:29 An: Vladan Gunjic Cc: ocfs2-users@oss.oracle.com Betreff: Re: [Ocfs2-users] ocfs2_search_chain: Group Descriptor has bad signature What version of ocfs2 is on the nodes? Do modinfo ocfs2 on all nodes. The version of OCFS2 shipped with SLES9 SP3 varies with kernel. Are you using the modules shipped by suse or building them yourself?

[PATCH 0/3] ocfs2: Switch over to JBD2.
ocfs2 currently uses the Journaled Block Device (JBD) for its journaling. This is a very stable and tested codebase. However, JBD is limited by architecture to 32bit block numbers. This means an ocfs2 filesystem is limited to 2^32 blocks. With a 4K blocksize, that's 16TB. People want larger volumes. Fortunately, there is now JBD2. JBD2 adds 64bit block number support and some other

[PATCH 0/40] ocfs2: Detach ocfs2 metadata I/O from struct inode
The following series of patches attempts to detach metadata I/O from struct inode. They are currently tied together pretty tightly. Metadata reads happen via the ocfs2_read_blocks() functions, writes via both jbd2 and ocfs2_write_blocks(). - Each inode has a cache of associated metadata blocks stored on its ip_metadata_cache member. The ocfs2_read/write_blocks() functions take a struct
