I saw that you guys reverted the patch with LP1846219 already. But for the sake of completeness, Stefan reverted the patch for upstream as well: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=964ce509e2ded52c1a61ad86044cc4d70abd9eb8 Regards, Jan -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1830731 Title: [19.10 FEAT] Thin provisioning base support (kernel+390tools) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1830731/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

--- Comment From stefan.haberl...@de.ibm.com 2019-10-01 09:15 EDT--- In addition to Jan's update to _not_ enable discard support I would recommend to completely revert the patch: 7e64db1597fe114b83fe17d0ba96c6aa5fca419a s390/dasd: Add discard support for ESE volumes to prevent the user from enabling the discard support for DASD devices. This patch will also be reverted upstream until further clarification.

--- Comment From hannsj_...@de.ibm.com 2019-10-01 08:40 EDT--- Comment from Jan Hoeppner 2019-09-24 07:16:57 CDT The thin provisioning feature introduces an IOCTL and the discard support to allow userspace tools and filesystems to release unused and previously allocated space respectively. During some internal performance improvements and further tests, the release of allocated space revealed some issues that may lead to data corruption in some configurations when filesystems are mounted with discard support enabled. As we're working on a fix and trying to clarify the situation, it is highly recommended at this point to _not_ enable discard for any filesystem when working with ESE DASDs. mkfs should also be called with discard disabled for ESE DASDs (e.g. mkfs.ext4 -E nodiscard /dev/dasdX). Fixes and clarifications will be provided as soon as possible.
