* glusterd, cli: handle uuid conflicts in probe gracefullyRaghavendra Bhat2012-07-023-3/+24
| | | | | | | | | | | | | | | | | | | | | | | A commonly faced problem among glusterfs users is: after a fresh installation of glusterfs in a virtual machine, the VM image is cloned to make multiple instances of the server. This breaks glusterd because right after glusterfs installation on the first boot glusterd would have created the node UUID and this gets inherited into the clone. The result is wierd behavior at the time of peer probe where glusterd does not (yet) deal with UUID collisions in a user friendly way. With this patch the peer which got the probe request will compare the uuid of the machine which send the probe request with its own uuid and send the proper error to cli if the uuids are same.

| | | | | | | | | | | | | | | | | | | | | The purpose of the ping timer is to assert the absence of any evidence the server is possibly alive. The current implementation updates the 'last_sent' timer in the following points in time, - rpc_clnt_submit: when rpc messages are being queued at the transport layer. (wrong!, since we have no way to determine if server actually received the message) - rpc_clnt_notify: when client receives pollout event on sending a message on the 'wire'. (correct, since it indicates ACK from server) The fix removes the 'incorrect' update of 'last_sent'.

* localtime and ctime are not MT-SAFEKaleb S. KEITHLEY2012-06-2922-265/+227
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of nit-level issues throughout the source with the use of localtime and ctime. While they apparently aren't causing too many problems, apart from the one in bz 828058, they ought to be fixed. Among the "real" problems that are fixed in this patch: 1) general localtime and ctime not MT-SAFE. There's a non-zero chance that another thread calling localtime (or ctime) will over-write the static data about to be used in another thread 2) localtime(& <64-bit-type>) or ctime(& <64-bit-type>) generally not a problem on 64-bit or little-endian 32-bit. But even though we probably have zero users on big-ending 32-bit platforms, it's still incorrect. 3) multiple nested calls passed as params. Last one wins, i.e. over- writes result of prior calls. 4) Inconsistent error handling. Most of these calls are for logging, tracing, or dumping. I submit that if an error somehow occurs in the call to localtime or ctime, the log/trace/dump still should still occur. 5) Appliances should all have their clocks set to UTC, and all log entries, traces, and dumps should use GMT. 6) fix strtok(), change to strtok_r() Other things this patch fixes/changes (that aren't bugs per se): 1) Change "%Y-%m-%d %H:%M:%S" and similar to their equivalent shorthand, e.g. "%F %T" 2) change sizeof(timestr) to sizeof timestr. sizeof is an operator, not a function. You don't use i +(32), why use sizeof(<var>). (And yes, you do use parens with sizeof(<type>).) 3) change 'char timestr[256]' to 'char timestr[32]' where appropriate. Per-thread stack is limited. Time strings are never longer than ~20 characters, so why waste 220+ bytes on the stack? Things this patch doesn't fix: 1) hodgepodge of %Y-%m-%d %H:%M:%S versus %Y/%m/%d-%H%M%S and other variations. It's not clear to me whether this ever matters, not to mention 3rd party log filtering tools may already rely on a particular format. Still it would be nice to have a single manifest constant and have every call to localtime/strftime consistently use the same format.

* protocol/client: Re-open should not have O_CREAT|O_TRUNC|O_EXCLPranith Kumar K2012-06-194-11/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA The bug is observed in 3.2.x because posix xlator changes the uid/gid of file as per frame->root-uid/gid if O_CREAT flag is set in open fop. Posix does not do this in 3.3.x so that bug does not appear anymore but this issue exposed the actual bug in client xlator re-open. Re-open of a file on re-connection should not perform re-open with the same flags at the time of open/create/opendir. Imagine a case where a file is opened with O_TRUNC|O_RDWR and some data is written to it, now if the brick goes down and comes back the file will be truncated. When I tested this case, the file is not truncated because locks xlator resets O_TRUNC unconditionally. Client xlator re-open bug and locks xlator bug cancel each other. Fix Reset O_CREAT|O_TRUNC|O_EXCL flags in re-open. Locks xlator should not reset O_TRUNC. Additional changes Removed wbflags as it is not assigned at all.

* gsyncd / geo-rep : failover/failbackCsaba Henk2012-06-133-66/+341
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit is based on Venky Shankar <vshankar@>'s original implementation. Let us first quote Venky's description, then we summarize changes to his work. ------ First version of failover/failback. Failback mechanism uses two exclusive modes: * blind-sync This mode works with xtime pairs (both master and slave) to identify candidated to sync the original master from the slave * wrapup-sync This mode is similar to the normal working of gsyncd except that orphaned entities in the gluster volume are not assigned xtimes. This prevents un-necessary transfer of data for such entities. Modes can be enabled via: gluster volume geo-replication M S config special_sync_mode blind gluster volume geo-replication M S config special_sync_mode wrapup To turn off the special modes (i.e. to revert to normal gsyncd behaviour) use: gluster volume geo-replication colon-d0 192.168.1.2::colon-d config \!special_sync_mode ------ Code has been refactored to meet following goals: - make checkpointing work with special sync modes - move out sync mode related conditionals from the crawl loop and make all decisions to be made at startup time - be intrusive to the crawl loop to smallest possible degree (we will have to change/revisit it for other reasons, and the complexity of that should not increase) So, xtime parsing/updating/evaluation that's specific to the certain special modes are represented as mixin classes; basic operation logic is in an abstract base class. On startup, special-sync-mode tunable is dynamically dispatched to the corresponding mixin and the actual master class is derived from the chosen mixin and the ABS.

* cluster/stripe: implement the coalesce stripe file formatBrian Foster2012-06-076-102/+882
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The coalesce file format for cluster/stripe condenses the striped files to a contiguous layout. The elimination of holes in striped files eliminates space wasted via local filesystem preallocation heuristics and significantly improves read performance. Coalesce mode is implemented with a new 'coalesce' xlator option, which is user-configurable and disabled by default. The format of newly created files is marked with a new 'stripe-coalesce' xattr. Cluster/stripe handles/preserves the format of files regardless of the current mode of operation (i.e., a volume can simultaneously consist of coalesced and non-coalesced files). Files without the stripe-coalesce attribute are assumed to have the traditional format to provide backward compatibility. extras/stripe-merge: support traditional and coalesce stripe formats Update the stripe-merge recovery tool to handle the traditional and coalesced file formats. The format of the file is detected automatically (and verified) via the stripe-coalesce attributes.

* glusterd: generate node UUID lazilyAnand Avati2012-06-0713-62/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A commonly faced problem among glusterfs users is: after a fresh installation of glusterfs in a virtual machine, the VM image is cloned to make multiple instances of the server. This breaks glusterd because right after glusterfs installation on the first boot glusterd would have created the node UUID and this gets inherited into the clone. The result is wierd behavior at the time of peer probe where glusterd does not (yet) deal with UUID collisions in a user friendly way. This patch is for the 'prevention' of the issue. The approach here is to avoid generating a UUID on the first start of glusterd, but instead generate a node UUID only when a node UUID is found to be necessary. This naturally avoids the creation of node UUID on first boot and prevents the issue to a large extent. This issue also needs a 'cure' patch, which gives more meaningful error messages to the user and provides CLI to recover from the situations (gluster peer reset?)

* libglusterfs : Fix validation for integer volume options.Kaushal M2012-06-073-10/+39
| | | | | | | | | | | | | | | | | | | | | Integer volume options which specified only the min value as 0, would not be validated during "volume set". The range check for an option happened only if both min and max were not 0. In the above case, even though a minium was specified, the range check did not happen as both min and max were 0. To allow forced validation in such cases, a new member, "validate", has been added to volume_options_t. This member takes the values GF_OPT_VALIDATE_BOTH, GF_OPT_VALIDATE_MIN and GF_OPT_VALIDATE_MAX (GF_OPT_VALIDATE_BOTH is the default).
