------- Comment From peter.oberparlei...@de.ibm.com 2019-03-25 05:32 EDT------- This error is likely due to using the full block device node (dasda) instead of a partition device node (e.g. dasda1) of a CDL formatted DASD device.
Note that the first two tracks (1 track = 48k at 4k block size) of a CDL-formatted DASD device have special properties. Not all data written to these blocks is retained. Instead portions of the data are replaced by an E5 byte pattern. Applications/FS should therefore not use the block device, but only partition devices. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821353 Title: bcache-super-show segfaults reading superblock on dasd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1821353/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
