[ceph-users] Re: The feasibility of mixed SSD and HDD replicated pool

2020-11-07 Thread Tony Liu
Is it FileStore or BlueStore? With this SSD-HDD solution, is journal or WAL/DB on SSD or HDD? My understanding is that, there is no benefit to put journal or WAL/DB on SSD with such solution.

[ceph-users] pg xyz is stuck undersized for long time

Hi all, I moved the crush location of 8 OSDs and rebalancing went on happily (misplaced objects only). Today, osd.1 crashed, restarted and rejoined the cluster. However, it seems not to re-join some PGs it was a member of. I have now undersized PGs for no real reason I would believe: PG_DEGRAD

NFS also works. I recommend NFS 4.1+ for performance reasons. On Sat, Nov 7, 2020 at 4:51 AM Marco Venuti wrote: > > Hi, > I have the same use-case. > Is there some alternative to Samba in order to export CephFS to the end > user? I am somewhat concerned with its potential security > vulnerabilit

Hi, I have the same use-case. Is there some alternative to Samba in order to export CephFS to the end user? I am somewhat concerned with its potential security vulnerabilities, which appear to be quite frequent. Specifically, I need server-side enforced permissions and possibly Kerberos authenticat
