Hi ! I respond to the list, as it may help others. I also reorder the response. > On Mon, Jan 18, 2021 at 2:41 PM Gilles Mocellin < > > gilles.mocellin@xxxxxxxxxxxxxx> wrote: > > Hello Cephers, > > > > On a new cluster, I only have 2 RBD block images, and the Dashboard > > doesn't manage to list them correctly. > > > > I have this message : > > Warning > > Displaying previously cached data for pool veeam-repos. > > > > Sometime it disappears, but as soon as I reload or return to the listing > > page, it's there. > > > > What I've seen, is a high CPU load due to ceph-mgr on the active > > manager. > > And also stack-traces like this : [...] > > dashboard.exceptions.ViewCacheNoDataException: ViewCache: unable to > > retrieve data > > > > I also see that, when I try to edit an image : > > > > 2021-01-18T11:13:26.383+0100 7f00199ca700 0 [dashboard ERROR > > frontend.error] > > (https://fidcl-mrs4-sto-sds.fidcl.cloud:8443/#/block/rbd/edit/veeam-> > repos%252Fveeam-repo2-vol1 > > <https://fidcl-mrs4-sto-sds.fidcl.cloud:8443/#/block/rbd/edit/veeam-repos% > > 252Fveeam-repo2-vol1>): Cannot read property 'features_name' of > > undefined > > > > TypeError: Cannot read property 'features_name' of undefined [...] > > > > But that's perhaps just becaus I open an Edit window on the image and it > > does not have the datas. > > The Edit window is empty, and I can't edit things, especially, I wan't > > to resize the image. > > [...] > > -- > > Gilles Le jeudi 21 janvier 2021, 21:56:58 CET Ernesto Puerta a écrit : > Hey Gilles, > > If I'm not wrong, that exception (ViewCacheNoDataException) happens when > the dashboard is unable to gather all required data from Ceph within a > defined timeout (5 secs I think, since the UI refreshes the data every ~5 > seconds). > > It'd be great if you could provide the steps to reproduce it and some > insights into your environment (number of RBD pools, number of RBD images, > snapshots, etc.). > > Kind Regards, > > Ernesto OK, As it is now, it always hapens, on the image listing, I have the Warning and the list is not always up to date, if I create an image, I must wait very long to see it. Also, I can not edit the 2 big images I have. Perhaps the size is important, they are 2 images of 40 TB. If I create a 1 GB test image, I can edit and resize it. But impossible withe the big image, the windows opens but all the fields are empty. Also, if it can matter, the images use a data pool (EC 3+2). I have 2 pools, a replicated one for metadatas veeam-repos (replic x3), and a data pool veeam-repos.data (EC 3+2). My cluster has 6 nodes with AMD 16 cores CPU, 128 GB RAM, 10 8 TB HDD. So 60 OSD. Soon doubling everything to 12 nodes. Usage, as the pool and image names can tell, is to mount RBD image as a XFS filesystem for a Veeam Backup Repository (krbd, because nbd-rbd tailed regularly, especially during fstrim). _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
