Hi Hartwig, I’m in a similar situation, did you ever get this fixed? -TJ On 29 Jan 2020, at 11:16, Hartwig Hauschild <ml-ceph@xxxxxxxxxxxx<mailto:ml-ceph@xxxxxxxxxxxx>> wrote: Hi, I had looked at the output of `ceph health detail` which told me to search for 'incomplete' in the docs. Since that said to file a bug (and I was sure that filing a bug did not help) I continued to purge the Disks that we hat overwritten and ceph then did some magic and told me that the PGs were again available on three OSDs but were incomplete. I have now gone ahead and marked all three of the OSDs where one of my incomplete PGs is (according to `ceph pg ls incomplete`) as lost one by one, waiting for ceph status to settle in between and that lead to the PG now being incomplete on three different OSDs. Also, force-create-pg tells me "already created".

There is also a command to force create PGs but I don’t think that will help in this case since you already have at least one copy.

We've recently started upgrading from luminous to nautilus, and for us that means we're retiring ceph-disk in favour of ceph-volume with lvm and dmcrypt. Our setup is in containers and we've got DBs separated from Data. When testing our upgrade-path we discovered that running the host on ubuntu-xenial and the containers on centos-7.7 leads to lvm inside the containers not using lvmetad because it's too old. That in turn means that not running `vgscan --cache` on the host before adding a LV to a VG essentially zeros the metadata for all LVs in that VG. That happened on two out of three hosts for a bunch of OSDs and those OSDs are gone. I have no way of getting them back, they've been overwritten multiple times trying to figure out what went wrong. So now I have a cluster that's got 16 pgs in 'incomplete', 14 of them with 0 objects, 2 with about 150 objects each. I have found a couple of howtos that tell me to use ceph-objectstore-tool to find the pgs on the active osds and I've given that a try, but ceph-objectstore-tool always tells me it can't find the pg I am looking for. Can I tell ceph to re-init the pgs? Do I have to delete the pools and recreate them? There's no data I can't get back in there, I just don't feel like scrapping and redeploying the whole cluster. -- Cheers, Hardy _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx<mailto:ceph-users@xxxxxxx> To unsubscribe send an email to ceph-users-leave@xxxxxxx<mailto:ceph-users-leave@xxxxxxx> -- Cheers, Hardy _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx<mailto:ceph-users@xxxxxxx> To unsubscribe send an email to ceph-users-leave@xxxxxxx<mailto:ceph-users-leave@xxxxxxx> _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
