Hello folks, While trying to make lvm work within a docker container I came across an issue when all lvcreate/lvremove got stuck indefinetly or until control-c. When I checked process I noticed lvm was waiting on one semaphore, I found that other folks hit similar issue and they fixed it by setting udev_sync and udev_rules to 0. It also helped my case too. I would greatly appreciate if you could share your thought if this change in future can potentially have any negative impact. Thank you
Hi To 'unblock' stuck processes waiting on udev cookie - you could run: 'dmsetup udevcomplete_all' However the key question is - how you could get stuck. That may need further debugging. You would need to expose your OS version and also version of lvm2 in use. Non working cookies are bad - and disabling udev sync is even more bad idea...
