Hi Ceph users,
I need to have different filesystem trees in different pools, mainly for
security reasons.
So I have ceph users (cephx) with specific access on specific pools.
I have one metadata pool ('metadata') and tree data pools ('data',
'wimi-files, 'wimi-recette-files').
I used file layouts ( http://ceph.com/docs/master/cephfs/file-layouts/ )
to associate directories with pools.
My filesystem looks like that :
Path -> associated pool
/ -> data
/prod -> wimi-files
/prod/... -> wimi-files
/recette -> wimi-recette-files
/recette/... -> wimi-recette-files
Is it the best way to achieve what I need, since it's not possible to
have multiple CephFS on a Ceph cluster ?
I ask this because my 'rados df' seems strange to me :
pool name category KB objects clones
degraded unfound rd rd KB wr wr
KB
data - 0 9045499 0
0 0 434686 434686 9294004 0
metadata - 58591 52681 0
0 0 2168219 2403048804 16461385 180433628
wimi-files - 9006435331 10169214 0
0 0 296284 2747513 19225407 9064999231
wimi-recette-files - 1036224 309167
0 0 0 345223 1401472 658388
1170762
total used 27404544372 19576561
total avail 78033398196
total space 105437942568
As you can see, there are 9045499 objects in 'data' pool, while there
are only two directories ( 'prod', 'recette' ), and not a single file in
this pool.
Anyone know how this works ?
Thanks in advance !
Regards
