Dear All,till now a selected group of VM's still seem to produce new stale file's and getting paused due to this.I've not updated gluster recently, however i did change the op version from 31200 to 31202 about a week before this issue arose.Looking at the .shard directory, i've 100.000+ files sharing the same characteristics as a stale file. which are found till now,they all have the sticky bit set, e.g. file permissions; ---------T. are 0kb in size, and have the trusted.glusterfs.dht.linkto attribute.
These are internal files used by gluster and do not necessarily mean they are stale. They "point" to data files which may be on different bricks (same name, gfid etc but no linkto xattr and no ----T permissions).
These files range from long a go (beginning of the year) till now. Which makes me suspect this was laying dormant for some time now..and somehow recently surfaced.Checking other sub-volumes they contain also 0kb files in the .shard directory, but don't have the sticky bit and the linkto attribute.Does anybody else experience this issue? Could this be a bug or an environmental issue?
These are most likely valid files- please do not delete them without double-checking.
Stale file handle errors show up when a file with a specified gfid is not found. You will need to debug the files for which you see this error by checking the bricks to see if they actually exist.
Also i wonder if there is any tool or gluster command to clean all stale file handles?Otherwise i'm planning to make a simple bash script, which iterates over the .shard dir, checks each file for the above mentioned criteria, and (re)moves the file and the corresponding .glusterfs file.If there are other criteria needed to identify a stale file handle, i would like to hear that.If this is a viable and safe operation to do of course.Thanks Olaf_______________________________________________Op do 20 dec. 2018 om 13:43 schreef Olaf Buitelaar <olaf.buitelaar@xxxxxxxxx>:Dear All,I figured it out, it appeared to be the exact same issue as described here; https://lists.gluster.org/pipermail/gluster-users/2018-March/033785.htmlAnother subvolume also had the shard file, only were all 0 bytes and had the dht.linktofor reference;[root@lease-04 ovirt-backbone-2]# getfattr -d -m . -e hex .shard/f28cabcb-d169-41fc-a633-9bef4c4a8e40.51500

vgchange -ay slave-datamkdir /mnt/slv01mount /dev/mapper/slave--data-lvol0 /mnt/slv01/Possible causes for this issue;1. the machine "lease-11" suffered from a faulty RAM module (ECC), which halted the machine and causes an invalid state. (this machine also hosts other volumes, with similar configurations, which report no issue)2. after the RAM module was replaced, the VM using the backing qemu image, was restored from a backup (the backup was file based within the VM on a different directory). This is because some files were corrupted. The backup/recovery obviously causes extra IO, possible introducing race conditions? The machine did run for about 12h without issues, and in total for about 36h.3. since only the client (maybe only gfapi?) reports errors, something is broken there?The volume info;root@lease-06 ~# gluster v info ovirt-backbone-2

Status : completedgluster version is @3.12.15 and cluster.op-version=31202========================It would be nice to know if it's possible to mark the files as not stale or if i should investigate other things?Or should we consider this volume lost?Also checking the code at; https://github.com/gluster/glusterfs/blob/master/xlators/features/shard/src/shard.c it seems the functions shifted quite some (line 1724 vs. 2243), so maybe it's fixed in a future version?Any thoughts are welcome.Thanks Olaf
