Adding Sahina for advice. Did you generate the ids file on the mount point. Ravi, can you help here? Okay, so what I understand from the output above is you have different gluster volumes mounted and some of them have incorrect permissions for the 'ids' file. The way to fix it is to do it from the mount like Nir said. Why did you delete the file from the .glusterfs in the brick(s)? Was there a gfid split brain? -Ravi > OK, it looks that sanlock can't work with empty file or rewrite them . > Am I right ?? Yes, the files must be initialized before sanlock can use them. You can initialize the file like this: sanlock direct init -s <sd_uuid>:0:repair/<sd_uuid>/dom_md/ids:0 Taken from http://lists.ovirt.org/pipermail/users/2016-February/038046.html > The last point - about "ids" workaround - this is offline version = VMs have to be moved out from for continual running with maintenance volume mode > But this is not acceptable in current situation, so the question again, is it safe to do it online ?? ( YES / NO ) The ids file is accessed only by sanlock. I guess that you don't have a running SPM on this DC, since sanlock fails to acquire a host id, so you are pretty safe to fix the permissions and initialize the ids files. I would do this: 1. Stop engine, so it will not try to start vdsm 2. Stop vdsm on all hosts, so they do not try to acquire a host id with sanlock This does not affect running vms 3. Fix the permissions on the ids file, via glusterfs mount 4. Initialize the ids files from one of the hosts, via the glusterfs mount This should fix the ids files on all replicas 5. Start vdsm on all hosts 6. Start engine Engine will connect to all hosts, hosts will connect to storage and try to acquire a host id. Then Engine will start the SPM on one of the hosts, and your DC should become up. David, Sahina, can you confirm that this procedure is safe? Yes, correcting from the mount point should fix it on all replicas Nir > > regs. > Pavel > > > > On 1.3.2016 18:38, Nir Soffer wrote: > > On Tue, Mar 1, 2016 at 5:07 PM, paf1(a)email.cz <paf1(a)email.cz&gt; wrote: >> >> Hello, can anybody explain this error no.13 ( open file ) in sanlock.log . > > > This is EACCES > > Can you share the outoput of: > > ls -lh /rhev/data-center/mnt/<server>:<_path>/<sd_uuid>/dom_md > >> >> >> The size of "ids" file is zero (0) > > > This is how we create the ids file when initializing it. > > But then we use sanlock to initialize the ids file, and it should be 1MiB after that. > > Is this ids files created by vdsm, or one you created yourself? > >> >> 2016-02-28 03:25:46+0100 269626 [1951]: open error -13 /rhev/data-center/mnt/glusterSD/localhost:_1KVM12-P4/7f52b697-c199-4f58-89aa-102d44327124/dom_md/ids >> 2016-02-28 03:25:46+0100 269626 [1951]: s187985 open_disk /rhev/data-center/mnt/glusterSD/localhost:_1KVM12-P4/7f52b697-c199-4f58-89aa-102d44327124/dom_md/ids error -13 >> 2016-02-28 03:25:56+0100 269636 [11304]: s187992 lockspace 7f52b697-c199-4f58-89aa-102d44327124:1:/rhev/data-center/mnt/glusterSD/localhost:_1KVM12-P4/7f52b697-c199-4f58-89aa-102d44327124/dom_md/ids:0 >> >> If the main problem is about zero file size, can I regenerate this file online securely , with no VM dependence ???? > > > Yes, I think I already referred to the instructions how to do that in a previous mail. > >> >> >> dist = RHEL - 7 - 2.1511 >> kernel = 3.10.0 - 327.10.1.el7.x86_64 >> KVM = 2.3.0 - 29.1.el7 >> libvirt = libvirt-1.2.17-13.el7_2.3 >> vdsm = vdsm-4.16.30-0.el7 >> GlusterFS = glusterfs-3.7.8-1.el7 >> >> >> regs. >> Pavel >> >> _______________________________________________ >> Users mailing list >> Users(a)ovirt.org >> http://lists.ovirt.org/mailman/listinfo/users >> > > _______________________________________________ Gluster-users mailing listGluster-users@gluster.orghttp://www.gluster.org/mailman/listinfo/gluster-users
