Unfortunately the problem is back in: Ubuntu 20.04.4 LTS Kernel: Linux 5.13.0-1027-oracle ocfs2-tools 1.8.6-2ubuntu1 open-iscsi 2.0.874-7.1ubuntu6.2 ... or was never solved an the solution before was just a lucky accident.
Meanwhile I have two servers, who never can mount an OCFS2 volume at the same time. Each single server can mount it, when it's not mounted on the other one. I did tests with all possible virtual machine shapes (AMD/Intel) and network adapters including hardware-assisted (SR-IOV) networking. The problem remained. The bug appears in Debian bug reports too: https://groups.google.com/g/linux.debian.bugs.dist/c/0xf2QXZOpE4 I tested the solution offered there and disabled all quotas on system and volume, but it had no effect. The problem remained. === A second problem appeared: It seems, that needed OCFS2 modules are no more present in in regular Ubuntu kernels for Oracle Cloud. After apt upgrades osfs2 and o2cb service do no more start: Apr 27 10:05:06 trans2 modprobe[759]: FATAL: Module ocfs2_stackglue not found in directory /lib/modules/5.13.0-1027-oracle Apr 27 10:05:06 trans2 modprobe[773]: FATAL: Module ocfs2_dlmfs not found in directory /lib/modules/5.13.0-1027-oracle Solution: apt install linux-modules-extra-5.13.0-1027-oracle Not really good in production environments, where upgrades can run automatically. Was this done by Oracle or by the Canonical team that builds the Images for Oracle? As far as I know, Oracle gets ready Images from Canonical. ** Changed in: ocfs2-tools (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1959581 Title: OCFS2 intermittently not mountable on a second Node in Ubuntu 20.04.3 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ocfs2-tools/+bug/1959581/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
