Hi,

Yesterday I was doing some TSM cleanup.  I found that we had >8000 orphaned 
filesystems for Linux clients that are all of a form like these:

("Days" is days since last backup)
TSM       Node          Days    FSID     Filesystem
tsm2    LITSMA4D        100     633     
/opt/kubernetes/data/docker/devicemapper/mnt/8659aedb3538a83019159cdb3d00842a4ace85adcd102be4147fa75c0957be60
tsm2    LITSMA4D        100     634     
/opt/kubernetes/data/docker/devicemapper/mnt/4905b5fb2e596d39f08b6ffc4a8a884a329f98df0b16938b866c31708a7ebe55
tsm2    LITSMA4D        100     635     
/opt/kubernetes/data/docker/devicemapper/mnt/c40c9bec3b01f0b839778ea2fa06b6b1eb07d9657fe9b41d9d9ecdbded07df32
tsm2    LITSMA5D        100     707     
/opt/kubernetes/data/docker/devicemapper/mnt/fdf32a2dc0048f7b7e9727afecc94d96504632365da88f71cf6509bfd8b08166
tsm2    LITSMA5D        100     708     
/opt/kubernetes/data/docker/devicemapper/mnt/4e17d69255758d1a09f79ee2c9cff06e3c73a852d51d144d28018ebbce9a38dc
tsm2    LITSMA5D        100     709     
/opt/kubernetes/data/docker/devicemapper/mnt/d7b497e5ee74a180f3a2a99c33a2af4ef3dbb57cd02b62b1dfd5cc6544c557d7

I think this is from an installed application, and we have no inhouse knowledge 
about Docker.  My guess is that these are container filesystems that the dsmc 
client swept up????

Questions:

Should these be backed up?
How would you exclude them since the filesystem name changes all the time?


Thanks!

Rick
