Hi Mauricio, thanks for your support. I have attached the requested information to the bug. I had to pseudomize some of the logical volume names because they are considered sensitive, but I did so in a consistent way so the structure should still be clear.
So that you don’t have to look through all details, here is a rough overview: There are six physical disks: 4 HDDs (sda, sdb, sdc, sdd) and 2 SSDs (sde, sdf). There are three DM RAID devices: - md0 is a RAID 1 that uses /dev/sda1, /dev/sdb1, /dev/sdc1, and /dev/sdd1. This device stores the boot partition. - md1 is a RAID 6 that uses /dev/sda2, /dev/sdb2, /dev/sdc2, and /dev/sdd2. This device is the only physical volume backing volume group vg0. - md2 is a RAID 1 that uses /dev/sde1 and /dev/sdf1. This device is used as the cache device (read/write) for Bcache. There are three LVM volume groups: - vg0 is backed by /dev/md0 and stores the root FS, the swap partition, a few LVs that are used for VMs, and an LV called vg2-backend, that is used by Bcache. - vg1 is backed by /dev/md2 and only has an LV called vg2-cache that is used by Bcache. - vg2 is backed by /dev/bcache0. It only contains LVs that are used for VMs. There is one Bcache device: - bcache0 is backed by /dev/vg0/vg2-backend (backend device) and /dev/vg1/vg2-cache (cache device). This device is used as the PV for vg2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867916 Title: Regression in kernel 4.15.0-91 causes kernel panic with Bcache To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1867916/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
