Hi, While upgrading a server with a CephFS mount tonight, it stalled on installing a new kernel, because it was waiting for `sync`. I'm pretty sure it has something to do with the CephFS filesystem which caused some issues last week. I think the kernel still has a reference to the probably lazy unmounted CephFS filesystem. Unmounting the filesystem 'works', which means it is no longer available, but the unmount-command seems to be waiting for sync() as well. Mounting the filesystem again doesn't work either. I know the simple solution is to just reboot the server, but the server holds quite a lot of VM's and Containers, so I'd prefer to fix this without a reboot. Anybody with some clever ideas? :) -- Kerio Operator in de Cloud? https://www.kerioindecloud.nl/ Mark Schouten | Tuxis Internet Engineering KvK: 61527076 | http://www.tuxis.nl/ T: 0318 200208 | info@xxxxxxxx
