It may be that a client or MDS is trying to connect to a target (OST or peer MDT) before that target is finished setup. Rather than spamming the console logs during initial connection, only print a console error message if there are repeated failures trying to connect to the target, which may indicate an error on that node.

The changes for LRU lock policy was introduced by commit bfae5a4e, where I was trying to revise the policy to pick locks for canceling. However, this caused two problems as mentioned in LU-5727. The first problem is that the lock can only be picked for canceling only if the number of LRU locks is over preset LRU number AND it's aged; the second problem is that mdc_cancel_weight() tends to not cancel OPEN locks, therefore open locks can be kept forever and finally exhausts memory on the MDT side. The commit 7b2d26b0 ("revert changes to ldlm_cancel_aged_policy") fixed the first problem. This patch will revert the rest of changes related to LRU policy revise. Signed-off-by:

To avoid scanning the replay open list every time in the ptlrpc_free_committed(), the fix of LU-2613 (4322e0f9) changed the ptlrpc_free_committed() to skip the open list unless the import generation is changed. That introduced a race which could make a closed open being replayed: 1. Application calls ll_close_inode_openhandle()-> mdc_close(), to close file, rq_replay is cleared, but the open request is still on the imp_committed_list; 2. Before the md_clear_open_replay_data() is called for close, client start replay, and that closed open will be replayed mistakenly; 3. Open replay interpret callback (mdc_replay_open) could race with the mdc_clear_open_replay_data() at the end; This patch fix the ptlrpc_free_committed() to make sure the open list is scanned on recovery to prevent the closed open request from being replayed.

small fixes: * when 'unplug' is set for ll_statahead(), sa_put() shouldn't kill the entry found, because its inflight RPC may not finish yet. * remove 'sai_generation', add 'lli_sa_generation' because the former one is not safe to access without lock. * revalidate_statahead_dentry() may fail to wait for statahead entry to become ready, in this case it should not release this entry, because it may be used by inflight statahead RPC. cleanups: * rename ll_statahead_enter() to ll_statahead(). * move dentry 'lld_sa_generation' update to ll_statahead() to simplify code and logic. * other small cleanups.

On some customer's systems, kernel was compiled with HZ defined to 100, instead of 1000. This improves performance for HPC applications. However, to use these systems with Lustre, customers have to re-build Lustre for the kernel because Lustre directly uses the defined constant HZ. Since kernel 2.6.21, some non-HZ dependent timing APIs become non- inline functions, which can be used in Lustre codes to replace the direct HZ access. These kernel APIs include: jiffies_to_msecs() jiffies_to_usecs() jiffies_to_timespec() msecs_to_jiffies() usecs_to_jiffies() timespec_to_jiffies() And here are some samples of the replacement: HZ -> msecs_to_jiffies(MSEC_PER_SEC) n * HZ -> msecs_to_jiffies(n * MSEC_PER_SEC) HZ / n -> msecs_to_jiffies(MSEC_PER_SEC / n) n / HZ -> jiffies_to_msecs(n) / MSEC_PER_SEC n / HZ * 1000 -> jiffies_to_msecs(n) This patch replaces the direct HZ access in lustre modules.

Once connected, the previously gathered AT statistics is not valid anymore because may reflect other routing, etc. The connect by itself could take a long time due to different reasons (e.g. server was not ready) and net latency got very high (see import_select_connection()) what does not reflect the current situation. Take into account only the current (re-)CONNECT rpc latency. Signed-off-by:

Extend the llite layer to support specifying individual target OSTs. Support specifying OSTs for regular files only. Directory support will be implemented later in a separate project. With this a file could have for example a OST index layout of 2,4,5,9,11. In addition, duplicate indices will be eliminated automatically. Calculate the max easize by ld_active_tgt_count instead of ld_tgt_count. However this may introduce problems when the OSTs are in recovery because non sufficient buffer may be allocated to store EA.

The pool related codes have some inconsistency about the length of pool name. Creating and setting a pool name of length 16 to a directory will succeed. However, creating a file under that directory will fail. This patch disables any pool name which is longer or equal to 16. And it changes LOV_MAXPOOLNAME from 16 to 15 which might cause some invalid LLOG records of OST pools with 16 byte names. It is not a problem since invalid LLOG records are just ignored. And OST pools with 16 byte names won't work well anyway on the old versions. There will be problem of inconsistency if part of the servers have this patch and part of the servers don't. But it would be safe to assume that this is not a normal configuration. Signed-off-by:
