Hi, we are planning an archive with cephfs containing 2 Petabytes of Data on 200 slow S-ATA Disks on a single cephfs with 150 subdirectories. The Disks will be around 80% full (570 TB of Data, 3-way replication). Since this is an archive most of the data will be written once and read only sometimes. Deletions are very seldom. Changes of the filesystem in general are not very often. The cephfs is exported via samba. Now I am thinking about how we can protect the data from accidental deletion or from malicious deletion from people knowing the login data. Also protection from administrator errors might be a good idea, imagine an admin on shell running an rsync --delete /usbdisk/ /cephfs/
This might help when using kernel cephfs mounts: https://docs.ceph.com/en/latest/cephfs/client-auth/#root-squash Gr. Stefan _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
