[Gluster-devel] Bitrot Review Request
Hi Pranith, You had a concern of consuming I/O threads when bit-rot uses rchecksum interface to signing, normal scrubbing and on-demand scrubbing with tiering. http://review.gluster.org/#/c/13833/5/xlators/storage/posix/src/posix.c As discussed over comments, the concern is valid and the above patch is not being taken in and would be abandoned. I have the following patch where the signing and normal scrubbing would not consume io-threads. Only the on-demand scrubbing consumes io-threads. I think this should be fine as tiering is single threaded and only consumes one I/O thread (as told by Joseph on PatchSet 6). http://review.gluster.org/#/c/13969/ Since, on-demand scrubbing is disabled by default and there is a size cap and we document to increase the default number of I/O threads, consuming one I/O thread for scrubbing would be fine I guess. Let me know your thoughts. Thanks and Regards, Kotresh H R ___ Gluster-devel mailing list Gluster-devel@gluster.org http://www.gluster.org/mailman/listinfo/gluster-devel

Re: [Gluster-devel] Possible bug in the communications layer ?
Hi Raghavendra, yes, the readv response contains xdata. The dict length is 38 (0x26) and, at the moment of failure, rsp.xdata.xdata_len already contains 0x26.

The data on the network seems ok (at least I haven't been able to identify any problem), so this must be a processing error on the client side. The last field in cut buffer of the sequentialized data corresponds to the length of the xdata field: 0x26. So at least 38 more byte should be present. Nice detective work, Xavi. It would be *very* interesting to see what the value of the "count" parameter is (it's unfortunately optimized out). I'll bet it's two, and iov[1].iov_len is 38. I have a weak memory of some problems with how this iov is put together, a couple of years ago, and it looks like you might have tripped over one more. It seems you are right. The count is 2 and the first 38 bytes of the second vector contains the remaining data of xdata field. This is the bug. client3_3_readv_cbk (and for that matter all the actors/cbks) expects response in utmost two vectors: 1. Program header containing request or response. This is subjected to decoding/encoding. This vector should point to a buffer that contains the entire program header/response contiguously. 2. If the procedure returns payload (like readv response or a write request), second vector contains the buffer pointing to the entire (contiguous) payload. Note that this payload is raw and is not subjected to encoding/decoding. In your case, this _clean_ separation is broken with part of program header slipping into 2nd vector supposed to contain read data (may be because of rpc fragmentation).

It seems a little odd that we turn the fop around immediately in EC, and that we have default_inodelk_cbk at frame 3. Could one of the DHT or EC people please take a look at it? Thanks! The part regarding to ec seems ok. This is uncommon, but can happen. When ec_gf_inodelk() is called, it sends a inodelk request to all its subvolumes. It may happen that the callbacks of all these requests are received before returning from ec_gf_inodelk() itself. This executes the callback inside the same thread of the caller. The reason why default_inodelk_cbk() is seen is because ec uses this function to report the result back to the caller (instead of calling STACK_UNWIND() itself). This seems what have happened here. The frames returned by ec to upper xlators are the same used by them (the frame in dht_blocking_lock() is the same that receives dht_blocking_inodelk_cbk()) and ec doesn't touch them, however the frame at 0x7fef1003ca5c is absolutely corrupted. We can see the call state from the core: (gdb) f 4 #4 0x7fef25c029a3 in ec_manager_inodelk (fop=0x7fef1000d37c, state=5) at /home/jenkins/root/workspace/regression-test-burn-in/xlators/cluster/ec/src/ec-locks.c:645 645 fop->cbks.inodelk(fop->req_frame, fop, fop->xl, (gdb) print fop->answer $30 = (ec_cbk_data_t *) 0x7fef180094ac (gdb) print fop->answer->op_ret $31 = 0 (gdb) print fop->answer->op_errno $32 = 0 (gdb) print fop->answer->count $33 = 6 (gdb) print fop->answer->mask $34 = 63 As we can see there's an actual answer to the request with a success result (op_ret == 0 and op_errno == 0) composed of the combination of answers from 6 subvolumes (count == 6). Looking at the dht code I have been unable to see any possible cause either. The test is doing renames where source and target directories are different. At the same time a new ec-set is added and rebalance started. Rebalance will cause dht to also move files between bricks. Maybe this is causing some race in dht ? I'll try to continue investigating when I have some time.

The default for nfs.disable is _only_ changing starting with GlusterFS-3.8. GlusterFS-3.8 HASN'T BEEN RELEASED YET.

So, at least in "theory" it shouldn't result in kernel panic. However infiniband also allows userspace programs to do somethings which can be done only by kernel (like pinning pages to a specific address). I am not very familiar with internals of infiniband and hence cannot authoritatively comment on whether kernel panic is possible/impossible.

Re: [Gluster-devel] How to enable ACL support in Glusterfs volume
Hi Niels, Now I am able to run 'setfacl' command on Gluster volume using Kenrel NFS. The problem was, I was exporting Gluster volume mount point which I get after mounting the gluster volume in /etc/exports file: like mount -t glusterfs -o acl :/ But instead of using this point I need to export the volume brick path i.e. '/tmp/brick/gv0' gluster volume info Volume Name: gv0 Type: Distribute Volume ID: c3d636aa-f718-47b2-90eb-2b5846ad52a2 Status: Started Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: 128.224.95.140:/tmp/brick/gv0 Options Reconfigured: nfs.disable: on performance.readdir-ahead: on and mount on remote as below: mount -t nfs -o acl,vers=3 128.224.95.140:/tmp/brick/gv0 then run setfacl -m u:nobody:rw / Now I have one question here, please answer it: Please let me confirm, is there any side effect to export brick path?

Re: [Gluster-devel] Possible bug in the communications layer ?
With your patch applied, it seems that the bug is not hit. I guess it's a timing issue that the new logging hides. Maybe no more data available after reading the partial readv header ? (it will arrive later). I'll continue testing...

Hi Raghavendra, yes, the readv response contains xdata. The dict length is 38 (0x26) and, at the moment of failure, rsp.xdata.xdata_len already contains 0x26. rsp.xdata.xdata_len having 0x26 even when decoding failed indicates that the approach used in socket.c to get the length of xdata is correct. However, I cannot find any other way of xdata going into payload vector other than xdata_len being zero. Just to be double sure, I've a patch containing debug message printing xdata_len when decoding fails in socket.c. Can you please apply the patch, run the tests and revert back with results?

Hi Jeff, On 28.04.2016 15:20, Jeff Darcy wrote: This happens with Gluster 3.7.11 accessed through Ganesha and gfapi. The volume is a distributed-disperse 4*(4+2). I'm able to reproduce the problem easily doing the following test: iozone -t2 -s10g -r1024k -i0 -w -F/iozone{1..2}.dat echo 3 >/proc/sys/vm/drop_caches iozone -t2 -s10g -r1024k -i1 -w -F/iozone{1..2}.dat The error happens soon after starting the read test. As can be seen in the data below, client3_3_readv_cbk() is processing an iovec of 116 bytes, however it should be of 154 bytes (the buffer in memory really seems to contain 154 bytes). The data on the network seems ok (at least I haven't been able to identify any problem), so this must be a processing error on the client side. The last field in cut buffer of the sequentialized data corresponds to the length of the xdata field: 0x26. So at least 38 more byte should be present. Nice detective work, Xavi. It would be *very* interesting to see what the value of the "count" parameter is (it's unfortunately optimized out). I'll bet it's two, and iov[1].iov_len is 38. I have a weak memory of some problems with how this iov is put together, a couple of years ago, and it looks like you might have tripped over one more. It seems you are right. The count is 2 and the first 38 bytes of the second vector contains the remaining data of xdata field. This is the bug. client3_3_readv_cbk (and for that matter all the actors/cbks) expects response in utmost two vectors: 1. Program header containing request or response. This is subjected to decoding/encoding. This vector should point to a buffer that contains the entire program header/response contiguously. 2. If the procedure returns payload (like readv response or a write request), second vector contains the buffer pointing to the entire (contiguous) payload. Note that this payload is raw and is not subjected to encoding/decoding. In your case, this _clean_ separation is broken with part of program header slipping into 2nd vector supposed to contain read data (may be because of rpc fragmentation). I think this is a bug in socket layer. I'll update more on this. Does your read response include xdata too? I think the code related to reading xdata in readv response is a bit murky. case SP_STATE_ACCEPTED_SUCCESS_REPLY_INIT: default_read_size = xdr_sizeof ((xdrproc_t) xdr_gfs3_read_rsp, &read_rsp); proghdr_buf = frag->fragcurrent; __socket_proto_init_pending (priv, default_read_size); frag->call_body.reply.accepted_success_state = SP_STATE_READING_PROC_HEADER; /* fall through */ case SP_STATE_READING_PROC_HEADER: __socket_proto_read (priv, ret); By this time we've read read response _minus_ the xdata I mean

Re: [Gluster-devel] [Gluster-users] gluster 3.7.9 permission denied and mv errors
Raghavendra, This error is occurring in a shell script moving files between directories on a FUSE mount when overwriting an old file with a newer file (it's a backup script, moving an incremental backup of a file into a 'rolling full backup' directory). As a temporary workaround, we parse the output of this shell script for move errors and handle the errors as they happen. Simply re-moving the files fails, so we stat the destination (to see if we can learn anything about the type of file that causes this behavior), delete the destination, and try the move again (success!). Typical output is as follows: /bin/mv: cannot move `./homegfs/hpc_shared/motorsports/gmics/Raven/p11/149/data_collected4' > to `../bkp00/./homegfs/hpc_shared/motorsports/gmics/ > Raven/p11/149/data_collected4': File exists > /bin/mv: cannot move > `./homegfs/hpc_shared/motorsports/gmics/Raven/p11/149/data_collected4' > to `../bkp00/./homegfs/hpc_shared/motorsports/gmics/ > Raven/p11/149/data_collected4': File exists > File: `../bkp00/./homegfs/hpc_shared/motorsports/gmics/ > Raven/p11/149/data_collected4' > Size: 1714Blocks: 4 IO Block: 131072 regular file > Device: 13h/19d Inode: 11051758947722304158 Links: 1 > Access: (0660/-rw-rw) Uid: ( 628/pkeistler) Gid: ( 2020/ gmirl) > Access: 2016-01-20 17:20:45.0 -0500 > Modify: 2015-11-06 15:20:41.0 -0500 > Change: 2016-01-27 03:35:00.434712146 -0500 > retry: renaming > ./homegfs/hpc_shared/motorsports/gmics/Raven/p11/149/data_collected4 > -> ../bkp00/./homegfs/hpc_shared/motorsports/gmics/Raven/p11/ > 149/data_collected4 > Not sure if that description rings any bells as to what the problem might be, but if not, I added some code to print out the 'getattr' for the source and destination file on all of the bricks (before we delete the destination) and will post to this thread the next time we have that issue.

[Gluster-devel] .glusterfs grown larger than volume content
Hello, We've noticed that the .glusterfs directory is larger than the contents of the volume. Our application only has access through the client so I don't suspect anything was deleted on the brick. # du -sh .glusterfs 31G .glusterfs/ # du -sh * 13G dir1 31M dir2 How could we have come into this state? Is there a way to find what is orphaned? We tried looking for any references to deleted files but it didn't seem to yield much: # find .glusterfs -links 1 -ls 2211630 lrwxrwxrwx 1 root root 51 Mar 4 14:34 .glusterfs/91/ff/91ffa-f20f-4933-a8d6-abx93074 -> ../../00/00/----0001/dir2 3835150 lrwxrwxrwx 1 root root 59 Mar 4 15:08 .glusterfs/b1/2d/bd5b5-e00c-4bd1-95c6-312a25 -> ../../7e/85/7cxxx90-88e9-4cdd-95fd-dd48/recyclebin 4494050 lrwxrwxrwx 1 root root 51 Mar 4 15:08 .glusterfs/21/28/2102-101e-4177-b775-74379ba -> ../../00/00/----0001/dir2 3941500 lrwxrwxrwx 1 root root 59 Apr 4 13:24 .glusterfs/c7/2b/c728-877-49a-b7d-3b3149c -> ../../e1/09/e10xx94e-c5xcd-4c1f-95f-4824106e/recyclebin 2299340 lrwxrwxrwx 1 root root 60 Mar 4 15:08 .glusterfs/00/00/----0006 -> ../../00/00/----0005/internal_op 2129310 lrwxrwxrwx 1 root root 8 Mar 4 15:08 .glusterfs/00/00/----0001 -> ../../.. 4775410 lrwxrwxrwx 1 root root 58 Mar 4 15:08 .glusterfs/00/00/----0005 -> ../../00/00/----0001/.trashcan 3850480 lrwxrwxrwx 1 root root 55 Mar 23 12:02 .glusterfs/b3/21/b3xxb20-4b23-4e93-8db4-3dxx8x6e -> ../../e1/09/e10084e-c5cd-4c1f-95f-482106e/videos 2199364 -rw-r--r-- 1 root root19 Apr 27 10:54 .glusterfs/health_check 2640270 -- 1 root root0 Apr 26 13:01 .glusterfs/indices/xattrop/xattrop-2198-d683-431-bxx2-103474 2129410 lrwxrwxrwx 1 root root 51 Mar 4 14:24 .glusterfs/e1/09/e1xxx4e-c5d-4c1f-95f-482xe -> ../../00/00/----0001/dir1 3976650 lrwxrwxrwx 1 root root 51 Mar 4 15:08 .glusterfs/7e/85/757c90-8e9-4cdd-95fd-dd48 -> ../../00/00/----0001/dir1 270337 20 -rw-r--r-- 1 root root20480 Dec 14 23:03 .glusterfs/data.db We are running on a single node but when I added a second node and perform a full heal, the .glusterfs directory size is the same as the volume content size which is that we expected.

[Gluster-devel] [IMPORTANT] Adding release notes for 3.8 features
Hi all, The branching for 3.8 will happen on April 30th, 2016. Since we are approaching the last stage for 3.8 release a public pad [1] is created for adding release notes. It should mention about major changes that may impact overall working of a feature. For example we are planning to depreciate gluster nfs from 3.8, i.e when volume get started, nfs server won't start by default.The user need to turn off "nfs.disable" option to bring up gluster nfs. So I kindly request all the feature owners to update the release note about their feature. Also please update your progress on 3.8 features in the roadmap [2] [1] https://public.pad.fsfe.org/p/glusterfs-3.8-release-notes [2] https://www.gluster.org/community/roadmap/3.8/ Thanks, Niels & Jiffin ___ Gluster-devel mailing list Gluster-devel@gluster.org http://www.gluster.org/mailman/listinfo/gluster-devel

Why this message appear in syslog? dht uses disk usage information from backend export. 1. What is the out put of du -hs ? Please get this information for each of the brick that are part of disperse. 2. Once you get du information from each brick, the value seen by dht will be based on how cluster/disperse aggregates du info (basically statfs fop). The reason for 100% disk usage may be, In case of 1, backend fs might be shared by data other than brick. In case of 2, some issues with aggregation. Is is safe to > ignore it? > dht will try not to have data files on the subvol in question (v0-disperse-56). Hence lookup cost will be two hops for files hashing to disperse-56 (note that other fops like read/write/open still have the cost of single hop and dont suffer from this penalty). Other than that there is no significant harm unless disperse-56 is really running out of space. regards, Raghavendra ___ > Gluster-devel mailing list > Gluster-devel@gluster.org > http://www.gluster.org/mailman/listinfo/gluster-devel > -- Raghavendra G ___ Gluster-devel mailing list Gluster-devel@gluster.org http://www.gluster.org/mailman/listinfo/gluster-devel
