Ravi, I did not yet modify the cluster.data-self-heal parameter to off because in the mean time node2 of my cluster had a memory shortage (this node has 32 GB of RAM) and as such I had to reboot it. After that reboot all locks got released and there are no more files left to heal on that volume. So the reboot of node2 did the trick (but this still seems to be a bug). Now on another volume of this same cluster I have a total of 8 files (4 of them being directories) unsynced from node1 and node3 (arbiter) as you can see below: Brick node1:/data/myvol-pro/brick /data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/dir11/oc_dir <gfid:3c92459b-8fa1-4669-9a3d-b38b8d41c360> /data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/le_dir <gfid:aae4098a-1a71-4155-9cc9-e564b89957cf> Status: Connected Number of entries: 4 Brick node2:/data/myvol-pro/brick Status: Connected Number of entries: 0 Brick node3:/srv/glusterfs/myvol-pro/brick /data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/dir11/oc_dir /data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/le_dir <gfid:aae4098a-1a71-4155-9cc9-e564b89957cf> <gfid:3c92459b-8fa1-4669-9a3d-b38b8d41c360> Status: Connected Number of entries: 4 If I check the "/data/dir1/dir2/dir3/dir4/dir5/dir6/dir7/dir8/dir9/dir10/" with an "ls -l" directory on the client (gluster fuse mount) I get the following garbage: drwxr-xr-x 4 www-data www-data 4096 Nov 5 14:19 . drwxr-xr-x 31 www-data www-data 4096 Nov 5 14:23 .. d????????? ? ? ? ? ? le_dir I checked on the nodes and indeed node1 and node3 have the same directory from the time 14:19 but node2 has a directory from the time 14:12. Again here the self-heal daemon doesn't seem to be doing anything... What do you recommend me to do in order to heal these unsynced files? ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Monday, November 5, 2018 2:42 AM, Ravishankar N <ravishankar@xxxxxxxxxx> wrote: > > > On 11/03/2018 04:13 PM, mabi wrote: > > > Ravi (or anyone else who can help), I now have even more files which are pending for healing. > > If the count is increasing, there is likely a network (disconnect) > problem between the gluster clients and the bricks that needs fixing. > > > Here is the output of a "volume heal info summary": > > Brick node1:/data/myvol-private/brick > > Status: Connected > > Total Number of entries: 49845 > > Number of entries in heal pending: 49845 > > Number of entries in split-brain: 0 > > Number of entries possibly healing: 0 > > Brick node2:/data/myvol-private/brick > > Status: Connected > > Total Number of entries: 26644 > > Number of entries in heal pending: 26644 > > Number of entries in split-brain: 0 > > Number of entries possibly healing: 0 > > Brick node3:/srv/glusterfs/myvol-private/brick > > Status: Connected > > Total Number of entries: 0 > > Number of entries in heal pending: 0 > > Number of entries in split-brain: 0 > > Number of entries possibly healing: 0 > > Should I try to set the "cluster.data-self-heal" parameter of that volume to "off" as mentioned in the bug? > > Yes, as mentioned in the workaround in the thread that I shared. > > > And by doing that, does it mean that my files pending heal are in danger of being lost? > > No. > > > Also is it dangerous to leave "cluster.data-self-heal" to off? > > No. This is only disabling client side data healing.
