Sorry for disturbing you... Uh, I met a very strange GlusterFS problem: I can access snapshots by using FUSE mount and it works fine. However, when I test Gluster USER-SERVICEABLE snapshots feature, I find I cannot see .snap directory in the NFS shared directory. So pls help me solve this problem, many thanks~
My Gluster version is glusterfs 8.6. My OS version is CentOS 7.9.2009 Here is gluster volume and snapshot info. ``` [root@pgsql-1 media-cifs]# gluster v info disperse_vol_2 Volume Name: disperse_vol_2 Type: Disperse Volume ID: a8bd1d15-20c0-43af-a66e-eb166bd92f4c Status: Started Snapshot Count: 5 Number of Bricks: 1 x (4 + 2) = 6 Transport-type: tcp Bricks: Brick1: pgsql-1:/run/gluster/snaps/1c51095f455d4b93b1dd2fcfdfdb6127/brick1/data Brick2: pgsql-2:/run/gluster/snaps/1c51095f455d4b93b1dd2fcfdfdb6127/brick2/data Brick3: pgsql-3:/run/gluster/snaps/1c51095f455d4b93b1dd2fcfdfdb6127/brick3/data Brick4: pgsql-1:/run/gluster/snaps/1c51095f455d4b93b1dd2fcfdfdb6127/brick4/data Brick5: pgsql-2:/run/gluster/snaps/1c51095f455d4b93b1dd2fcfdfdb6127/brick5/data Brick6: pgsql-3:/run/gluster/snaps/1c51095f455d4b93b1dd2fcfdfdb6127/brick6/data Options Reconfigured: features.show-snapshot-directory: on features.snapshot-directory: .snaps_disperse_vol_2 features.uss: enable storage.fips-mode-rchecksum: on transport.address-family: inet nfs.disable: on features.quota: off features.inode-quota: off features.quota-deem-statfs: off features.barrier: disable snap-activate-on-create: disable cluster.enable-shared-storage: enable ``` Here is the snapshot info: ``` [root@pgsql-1 media-cifs]# gluster snap info snap_disperse_vol_2_test1 Snapshot : snap_disperse_vol_2_test1 Snap UUID : 8cab3954-3055-43aa-b34f-bbff58375881 Created : 2021-12-21 09:23:43 Snap Volumes: Snap Volume Name : 4dd90c9a08f1449fb865a368676ebd61 Origin Volume name : disperse_vol_2 Snaps taken for disperse_vol_2 : 5 Snaps available for disperse_vol_2 : 251 Status : Started ``` But I can not see any .snaps directory in the media3 directory. ``` [root@pgsql-1 media-cifs]# mount -t nfs 10.10.10.1:/disperse_vol_2 /media3/ [root@pgsql-1 media-cifs]# ls -a /media3 . 21.txt 24.txt 27.txt 2.txt 32.txt 35.txt .. 22.txt 25.txt 28.txt 30.txt 33.txt 36.txt ``` I can access snapshot by using FUSE mount and it works fine. ``` [root@pgsql-1 media-cifs]# mount -t glusterfs 10.10.10.1:/snaps/snap_disperse_vol_2_test1/disperse_vol_2 /mnt/snap/ [root@pgsql-1 media-cifs]# ls /mnt/snap/ 20.txt 23.txt 26.txt 29.txt 31.txt 34.txt 37.txt 3.txt 42.txt 45.txt 48.txt 50.txt 7.txt 21.txt 24.txt 27.txt 2.txt 32.txt 35.txt 38.txt 40.txt 43.txt 46.txt 49.txt 5.txt 8.txt 22.txt 25.txt 28.txt 30.txt 33.txt 36.txt 39.txt 41.txt 44.txt 47.txt 4.txt 6.txt 9.txt ``` I haven't any clues to solve this problems, pls help me. tks~ -- Lee.T
