[ceph-users] MDS assert failed when shutting down

Hi Cephers, We occasionally meet an assertion failure when trying to shutdown an MDS, as followings: -14> 2017-01-22 14:13:46.833804 7fd210c58700 2 -- 192.168.36.11:6801/2188363 >> 192.168.36.48:6800/42546 pipe(0x558ff3803400 sd=17 :52412 s=4 pgs=227 cs=1 l=1 c=0x558ff3758900).fault (0) Su

[ceph-users] mds reconnect timeout

Hi John, In our environment we want to deploy MDS and cephfs client on the same node (users actually use cifs/nfs to access ceph storage). However, it takes a long time to recover if the node with active MDS fails, during which a large part is for the new MDS waiting for all clients reconnect. T

Re: [ceph-users] CephFS and WORM

Thank you for the confirmation, John! As we have both CIFS&NFS users, I was wishing the feature should be implemented at the CephFS layer :< Regards, ---Sandy > -Original Message- > From: John Spray [mailto:jsp...@redhat.com] > Sent: Monday, July 11, 2016 7:28 PM >

[ceph-users] CephFS and WORM

Hi Cephers, I’m planning to set up samba/nfs based on CephFS kernel mount. The WORM(write once read many) feature is required but I’m not sure if CephFS officially supports it, any suggestions? Thanks in advance. Regards, ---Sandy

Re: [ceph-users] How to change setting for tunables "require_feature_tunables5"

Hi Andrey, You may change your cluster to a previous version of crush profile (e.g. hammer) by command: `ceph osd crush tunables hammer` Or, if you want to only switch off the tunables5, do as the following steps (not sure if there is a simpler way :<) 1. `ceph osd getcrushmap -o crushmap` 2. `

Re: [ceph-users] RadosGW - Problems running the S3 and SWIFT API at the same time

Hi, I'm not running a cluster as yours, but I don't think the issue is caused by you using 2 APIs at the same time. IIRC the dash thing is append by S3 multipart upload, with a following digit indicating the number of parts. You may want to check this reported in s3cmd community: https://sourcef

[ceph-users] About the NFS on RGW

Hi Matt & Cephers, I am looking for advise on setting up a file system based on Ceph. As CephFS is not yet productive ready(or I missed some breakthroughs?), the new NFS on RadosGW should be a promising alternative, especially for large files, which is what we are most interested in. However, a

[ceph-users] rgw potential security issue

Hi Cephers, Recently when I did some tests of RGW functions I found that the swift key of a subuser is kept after removing the subuser. As a result, this subuser-swift_key pair can still pass authentication system and get an auth-token (without any permission though). Moreover, if we create a s
