* cluster/dht: Correct min_free_disk behaviourv3.3.2qa2Varun Shastry2013-04-172-27/+90
| | | | | | | | | | | | | | | | | | | | | | | | Problem: Files were being created in subvol which had less than min_free_disk available even in the cases where other subvols with more space were available. Solution: Changed the logic to look for subvol which has more space available. In cases where all the subvols have lesser than Min_free_disk available , the one with max space and atleast one inode is available. Known Issue: Cannot ensure that first file that is created right after min-free-value is crossed on a brick will get created in other brick because disk usage stat takes some time to update in glusterprocess. Will fix that as part of another bug.

* dht: improve transform/detransform of d_off (and be ext4 safe)shishir gowda2013-04-161-5/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backporting Avati's fix http://review.gluster.org/4711 The scheme to encode brick d_off and brick id into global d_off has two approaches. Since both brick d_off and global d_off are both 64-bit wide, we need to be careful about how the brick id is encoded. Filesystems like XFS always give a d_off which fits within 32bits. So we have another 32bits (actually 31, in this scheme, as seen ahead) to encode the brick id - which is typically plenty. Filesystems like the recent EXT4 utilize the upto 63 low bits in d_off, as the d_off is calculated based on a hash function value. This leaves us no "unused" bits to encode the brick id. However both these filesystmes (EXT4 more importantly) are "tolerant" in terms of the accuracy of the value presented back in seekdir(). i.e, a seekdir(val) actually seeks to the entry which has the "closest" true offset. This "two-prong" scheme exploits this behavior - which seems to be the best middle ground amongst various approaches and has all the advantages of the old approach: - Works against XFS and EXT4, the two most common filesystems out there. (which wasn't an "advantage" of the old approach as it is borken against EXT4) - Probably works against most of the others as well. The ones which would NOT work are those which return HUGE d_offs _and_ NOT tolerant to seekdir() to "closest" true offset. - Nothing to "remember in memory" or evict "old entries". - Works fine across NFS server reboots and also NFS head failover. - Tolerant to seekdir() to arbitrary locations. Algorithm: Each d_off can be encoded in either of the two schemes. There is no requirement to encode all d_offs of a directory or a reply-set in the same scheme. The topmost bit of the 64 bits is used to specify the "type" of encoding of this particular d_off. If the topmost bit (bit-63) is 1, it indicates that the encoding scheme holds a HUGE d_off. If the topmost bit is is 0, it indicates that the "small" d_off encoding scheme is used. The goal of the "small" d_off encoding is to stay as dense as possible towards the lower bits even in the global d_off. The goal of the HUGE d_off encoding is to stay as accurate (close) as possible to the "true" d_off after a round of encoding and decoding. If DHT has N subvolumes, we need ROOF(Log2(N)) "bits" to encode the brick ID (call it "n"). SMALL d_off =========== Encoding -------- If the top n + 1 bits are free in a brick offset, then we leave the top bit as 0 and set the remaining bits based on the old formula: hi_mask = 0xffffffffffffffff hi_mask = ~(hi_mask >> (n + 1)) if ((hi_mask & d_off_brick) != 0) do_large_d_off_encoding () d_off_global = (d_off_brick * N) + brick_id Decoding -------- If the top bit in the global offset is 0, it indicates that this is the encoding formula used. So decoding such a global offset will be like the old formula: if ((d_off_global & 0x8000000000000000) != 0) do_large_d_off_decoding() d_off_brick = (d_off_global % N) brick_id = d_off_global / N HUGE d_off ========== Encoding -------- If the top n + 1 bits are NOT free in a given brick offset, then we set the top bit as 1 in the global offset. The low n bits are replaced by brick_id. low_mask = 0xffffffffffffffff << n // where n is ROOF(Log2(N)) d_off_global = (0x8000000000000000 | d_off_brick & low_mask) + brick_id if (d_off_global == 0xffffffffffffffff) discard_entry(); Decoding -------- If the top bit in the global offset is set 1, it indicates that the encoding formula used is above. So decoding would look like: hi_mask = (0xffffffffffffffff << n) low_mask = ~(hi_mask) d_off_brick = (global_d_off & hi_mask & 0x7fffffffffffffff) brick_id = global_d_off & low_mask If "losing" the low n bits in this decoding of d_off_brick looks "scary", we need to realize that till recently EXT4 used to only return what can now be expressed as (d_off_global >> 32). The extra 31 bits of hash added by EXT recently, only decreases the probability of a collision, and not eliminate it completely, anyways. In a way, the "lost" n bits are made up by decreasing the probability of collision by sharding the files into N bricks / EXT directories -- call it "hash hedging", if you will :-) Change-Id: I9551c581c3f3d4c9e719764881036d554f60c557 Thanks-to: Zach Brown <zab@redhat.com> BUG: 838784 Signed-off-by: shishir gowda <sgowda@redhat.com> Reviewed-on: http://review.gluster.org/4799 Reviewed-by: Amar Tumballi <amarts@redhat.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-on: http://review.gluster.org/4822

* cluster/afr: Preserve mtime in self-healPranith Kumar K2013-04-102-14/+76
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: Data self-heal may choose sink iatt to set mtimes. This happens because after syncing of data is done self-heal does one more xattrops/fstat to determine sources sinks to set the inode-ctx. Since this is done after data syncing and erase of xattrs, old source and old sink are now sources, but the mtimes of them differ. Old code just takes the first source from the list and update mtimes, which could be sink before the self-heal started. Fix: Set mtime from 'sources before syncing'.

* localtime and ctime are not MT-SAFEKaleb S. KEITHLEY2013-02-0821-256/+228
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

And while the libc in RHEL 6 does have fallocate(2), the version of fuse in RHEL 6 does not support fallocate, and things are handled gracefully elsewhere (the kernel perhaps?) N.B. fallocate was added to version 7.19 of fuse. Fedora 17 and later (and maybe earlier too) has 7.19. RHEL 6 still has 7.13. Glusterfs uses the 7.13 version <linux/fuse.h> (in contrib/fuse-include/fuse_kernel.h) Thus on Fedora 17, with both fallocate(2) in libc and fallocate support in fuse, the fallocate invocation is dispatched to glusterfs, but the dispatch table (fuse_std_ops in xlators/mount/fuse/src/fuse-bridge.c) is too short for one thing; the fallocate opcode (43) indexes beyond the end of the table, and even when that doesn't directly cause a SEGV, the NULL pointer at that location does cause a SEGV when attempting to call the function through the pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
