Now that we are 2 years and some ceph releases farther and have bluestor: Are there meanwhile any better ways to find out the mtime of an rbd image ? Thanks Christoph On Thu, Nov 26, 2015 at 06:50:46PM +0100, Jan Schermer wrote: > Find in which block the filesystem on your RBD image stores

While certainly that could be a feature that could be added to "rbd info", it will take a while for this feature to reach full use since it would rely on new versions of librbd / krbd. Additionally, access and modified timestamps would require sending out an update notification so that other

Hi, YMMV, riddled with assumptions (image is image-format=2, has one ext4 filesystem, no partition table, ext4 superblock starts at 0x400 and probably a whole boatload of other stuff, I don't know when ext4 updates s_wtime of it's superblock, nor if it's actually the superblock last write or last

Re: [ceph-users] Modification Time of RBD Images

Hi jason, do you think this is a good feature for rbd? maybe we can implement a "rbd stat" command to show atime, mtime and ctime of an image. Yang On 03/23/2017 08:36 PM, Christoph Adomeit wrote: Hi, no i did not enable the journalling feature since we do not use mirroring. On Thu,

Did you enable the journaling feature? On 03/23/2017 07:44 PM, Christoph Adomeit wrote: Hi Yang, I mean "any write" to this image. I am sure we have a lot of not-used-anymore rbd images in our pool and I am trying to identify them. The mtime would be a good hint to show which images might

Hi Yang, I mean "any write" to this image. I am sure we have a lot of not-used-anymore rbd images in our pool and I am trying to identify them. The mtime would be a good hint to show which images might be unused. Christoph On Thu, Mar 23, 2017 at 07:32:49PM +0800, Dongsheng Yang wrote: > Hi

Hello List, i am wondering if there is meanwhile an easy method in ceph to find more information about rbd-images. For example I am interested in the modification time of an rbd image. I found some posts from 2015 that say we have to go over all the objects of an rbd image and find the

Find in which block the filesystem on your RBD image stores journal, find the object hosting this block in rados and use its mtime :-) Jan > On 26 Nov 2015, at 18:49, Gregory Farnum wrote: > > I don't think anything tracks this explicitly for RBD, but each RADOS object >
