Description of problem: Wile updating a mageia 8 system today, I got a huge series (probably about 40 lines) of errors like ERROR: pdc: reading /dev/dm-1[Input/outiut error] ERROR: pdc: reading /dev/dm-1[Input/output error] I beoive they were occuring at the beginning of setting up the new kernel. I have no idea what they mean of what /dev/dm-1 is supposed to be. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3.

/dev/dm-1 is the first block device created by device mapper. https://en.wikipedia.org/wiki/Device_mapper Are you using an encrypted file system, raid, lvm, docker, or another one of the applications listed on the wiki page?

I have a number of cryptmount files and I bind mount a number of directories into other directories. How do I find out what dm-1 is used for? Does it matter if I got all those errors?
I just did an rpm -e on a bunch of old kernels and again got a huge list of those dm-1 input/output errors.
Source RPM: kernel? kernel-desktop-5.15.43-1.mga8-1-1.mga8 => kernel? kernel-desktop-5.15.65-1.mga8-1-1.mga8
You should have a look at "man dmsetup", "man dmraid" or whatever tool you used to setup your crypt/llvm/raid/(whatever) to find the (logical)device dm-1. This error message can have different causes: - failing drive - to small power supply for a drive - unstable power supply for a drive - cable problems - ...
I was mistaken above. dm-1 is the second device mapper entry as it starts at dm-0 To figure out which device/partition it is, use "cryptsetup status /dev/dm-1" and look for the device line.
>sudo cryptsetup status /dev/dm-1 /dev/dm-1 is active and is in use. type: n/a That's it. For dm-0 I get >sudo cryptsetup status /dev/dm-0 /dev/dm-0 is active and is in use. type: n/a cipher: aes-cbc-plain keysize: 256 bits key location: dm-crypt device: /dev/loop0 loop: /fastlocal/encrypt/varspoolmail1 sector size: 512 offset: 0 sectors size: 4096000 sectors mode: read/write
What's in /etc/fstab, /etc/crypttab, /etc/cryptmount/cmtab, /etc/lvm/lvm.conf, and the output of "journalctl -b --no-h|grep -e crypt -e dm-"?
Also attach the output of dmesg
dmesg has nothing at the time that I installed the new kernel, but about an hour earlier ( and also a few days earlier) there were a whole bunch of errors [2482454.740668] Buffer I/O error on dev dm-1, logical block 3839999, async page read and about 20 days earlier as well. In Journalctl, there were a also a whole bunch of such errors.

What's the output of "ll /dev/mapper" and blkid run as root?

I'm not sure if that is part of the problem or not.
Is this still an isue?
