* afr: Avoid excessive logging in self-heal.Krishnan Parthasarathi2012-08-236-22/+25
| | | | | | | | | | | | | | - (Excessive) Logging has been very useful as 'bread-crumbs' in many a root-cause analyses. This patch aims at avoiding logging when the information could be reconstructed using the xattrs, statedump, and/or "volume heal" CLI commands.

This would help us to continue with the _extra_ work (like healing gfid as of now) in fuse_lookup_resume.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA: When an fd is opened while a brick is down, after the brick comes back up afr issues open on the other brick. It can fail for a number of reasons (enoent etc). While the system is in that state, inode/entrylks pre-op happen only on the brick that is up and fd is opened for fd-fops. post-op should consider only the bricks where both pre-op and fop succeeded as success, rest of them as failures. Code now marks only the children that are down as failures as opposed to child_down & fd-not-opened. This makes change-log appear as success on the subvolume where we did not do any fop leading to no change-log but differences in data/metadata for reg-files. Fix: Mark non-participants of fop as failure. This is tracked in transaction.pre_op[]. Tests: Simulated the scenario using err-gen on top of one of the client xlator which fails all fops always. Performed fops and the changelog represented pending fops on the brick with err-gen loaded. Tested the case of brick down and perform entry/metadata/data operations to confirm they still work as expected.

Test if ret is negative, in which case the control would anyway branch to the label fail where the function returns. Otherwise dict_len is assigned with ret, in turn giving a more meaningful value to the attribute length. TEST: Attached gdb to glusterfs mount process, set breakpoint at client_setvolume, forced dict_serialized_length to return -EINVAL (indirectly by forcing _dict_serialized_length to return -EINVAL after setting count to -1 within its body) and checked the value of ret (which is now sure to contain a negative value) whose value will be appropriately tested to decide the next course of action within client_setvolume: whether to simply exit due to an error or execute the subsequent statements.

| | | | | | | | | | | | | | | | | | | | | | | | | RCA: Afr crashes when a last fop response fails and 'fop output' arguments are NULL. Afr does not handle these gracefully. Fix: Changed the fops to not access the 'fop output' arguments in case of failures. Tests: Changed afr wind_cbk code to fail the last response by setting op_ret as -1 and op_errno as ENOMEM and setting all other output variables as NULL to test the change. Removed the code to verify success cases. No crashes or errors seen.

* cluster/stripe: handle short writes and errors in writev callbackBrian Foster2012-07-303-38/+106
| | | | | | | | | | | | | | | | | | | | | | | cluster/stripe write callback handling is broken in the event of server side errors and short writes due to crudely summing up the return values from each node. This can produce incorrect results or cause an application to rewrite the wrong portions of a buffer in an attempt to handle this condition. Modify cluster/stripe writev handling to record the requested size of each write and use this data to return the number of consecutive bytes written from the original request. This allows an application to retry a write at the point of error (and potentially consume said error).

This affects other fops with conflicting inode, entry locks with self-heal. Fix: This patch provides configuring enable/disable of least-priority. Additional changes: Moved RCHECKSUM fop to low instead of least because it will still affect the performance of other fops if RCHECKSUM is in LEAST priority. Tests: Tested that the enabling/disabling of fops is working fine. Tested that RCHECKSUM fop priority is assigned LOW when least-priority is disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA The bug is observed because the decision to mark a file in split-brain is taken outside appropriate locks. Lookup gathers xattrs outside any lock. The xattrs being in split-brain in lookup should only be taken as a hint. Appropriate inodelks should be taken before confirming a split-brain. Self-heal confirms this at the moment. If data/metadata self-heal is turned off, inspecting of xattrs could not be performed so split-brain behavior does not work correctly if the self-heal options are turned off. Fix Self-heals are launched to inspect xattrs even when the data/metadata self-heal options are turned off. The decision to heal data/metadata after the xattrs are inspected is based on whether the options are turned on/off. So decision to set/reset split-brain flag is taken inside appropriate locks.
