* pNFS: return status from nfs4_pnfs_ds_connectWeston Andros Adamson2017-03-171-1/+1
| | | | | | | | | | | | | | | The nfs4_pnfs_ds_connect path can call rpc_create which can fail or it can wait on another context to reach the same failure. This checks that the rpc_create succeeded and returns the error to the caller. When an error is returned, both the files and flexfiles layouts will return NULL from _prepare_ds(). The flexfiles layout will also return the layout with the error NFS4ERR_NXIO. Signed-off-by: Weston Andros Adamson <dros@primarydata.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>

* pNFS: Enable layoutreturn operation for return-on-closeTrond Myklebust2016-12-011-16/+14
| | | | | | | | | | Amend the pnfs return on close helper functions to enable sending the layoutreturn op in CLOSE/DELEGRETURN. This closes a potential race between CLOSE/DELEGRETURN and parallel OPEN calls to the same file, and allows the client and the server to agree on whether or not there is an outstanding layout.

* pnfs: add a new mechanism to select a layout driver according to an ordered listJeff Layton2016-09-191-2/+3
| | | | | | | | | | | | | | | | | | Currently, the layout driver selection code always chooses the first one from the list. That's not really ideal however, as the server can send the list of layout types in any order that it likes. It's up to the client to select the best one for its needs. This patch adds an ordered list of preferred driver types and has the selection code sort the list of available layout drivers according to it. Any unrecognized layout type is sorted to the end of the list. For now, the order of preference is hardcoded, but it should be possible to make this configurable in the future.

* pnfs: track multiple layout types in fsinfo structureJeff Layton2016-09-191-2/+2
| | | | | | | | | | | | | | | Current NFSv4.1/pNFS client assumes that MDS supports only one layout type. While it's true for most existing servers, nevertheless, this can be change in the near future. For now, this patch just plumbs in the ability to track a list of layouts in the fsinfo structure. The existing behavior of the client is preserved, by having it just select the first entry in the list.

* pnfs: rework LAYOUTGET retry handlingJeff Layton2016-05-171-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several problems in the way a stateid is selected for a LAYOUTGET operation: We pick a stateid to use in the RPC prepare op, but that makes it difficult to serialize LAYOUTGETs that use the open stateid. That serialization is done in pnfs_update_layout, which occurs well before the rpc_prepare operation. Between those two events, the i_lock is dropped and reacquired. pnfs_update_layout can find that the list has lsegs in it and not do any serialization, but then later pnfs_choose_layoutget_stateid ends up choosing the open stateid. This patch changes the client to select the stateid to use in the LAYOUTGET earlier, when we're searching for a usable layout segment. This way we can do it all while holding the i_lock the first time, and ensure that we serialize any LAYOUTGET call that uses a non-layout stateid. This also means a rework of how LAYOUTGET replies are handled, as we must now get the latest stateid if we want to retransmit in response to a retryable error. Most of those errors boil down to the fact that the layout state has changed in some fashion. Thus, what we really want to do is to re-search for a layout when it fails with a retryable error, so that we can avoid reissuing the RPC at all if possible. While the LAYOUTGET RPC is async, the initiating thread always waits for it to complete, so it's effectively synchronous anyway. Currently, when we need to retry a LAYOUTGET because of an error, we drive that retry via the rpc state machine. This means that once the call has been submitted, it runs until it completes. So, we must move the error handling for this RPC out of the rpc_call_done operation and into the caller. In order to handle errors like NFS4ERR_DELAY properly, we must also pass a pointer to the sliding timeout, which is now moved to the stack in pnfs_update_layout. The complicating errors are -NFS4ERR_RECALLCONFLICT and -NFS4ERR_LAYOUTTRYLATER, as those involve a timeout after which we give up and return NULL back to the caller. So, there is some special handling for those errors to ensure that the layers driving the retries can handle that appropriately.

* pnfs: only tear down lsegs that precede seqid in LAYOUTRETURN argsJeff Layton2016-05-171-2/+4
| | | | | | | | | | | LAYOUTRETURN is "special" in that servers and clients are expected to work with old stateids. When the client sends a LAYOUTRETURN with an old stateid in it then the server is expected to only tear down layout segments that were present when that seqid was current.

* pnfs: keep track of the return sequence number in pnfs_layout_hdrJeff Layton2016-05-171-0/+1
| | | | | | | | | | | | | | | When we want to selectively do a LAYOUTRETURN, we need to specify a stateid that represents most recent layout acquisition that is to be returned. When we mark a layout stateid to be returned, we update the return sequence number in the layout header with that value, if it's newer than the existing one. Then, when we go to do a LAYOUTRETURN on layout header put, we overwrite the seqid in the stateid with the saved one, and then zero it out.

* NFSv4.1/pnfs: Fix a close/delegreturn hang when return-on-close is setTrond Myklebust2015-08-181-4/+3
| | | | | | | | | | | | | | | | | | | | | The helper pnfs_roc() has already verified that we have no delegations, and no further open files, hence no outstanding I/O and it has marked all the return-on-close lsegs as being invalid. Furthermore, it sets the NFS_LAYOUT_RETURN bit, thus serialising the close/delegreturn with all future layoutget calls on this inode. The checks in pnfs_roc_drain() for valid layout segments are therefore redundant: those cannot exist until another layoutget completes. The other check for whether or not NFS_LAYOUT_RETURN is set, actually causes a hang, since we already know that we hold that flag. To fix, we therefore strip out all the functionality in pnfs_roc_drain() except the retrieval of the barrier state, and then rename the function accordingly.
