And more recently read errors followed by: 10 -- 41 05 40 00 00 60 d9 6e 08 00 00 Error: IDNF at LBA = 0x60d96e08 = 1624862216 548 hours is not an old drive. It shouldn't have any write errors. But as a drive ages there might be some and they should be handled transparently and not affect any other operation. Something is definitely wrong that there are write errors followed by read errors followed by this IDNF error which suggests the drive is having problems read its own data written to sectors reserved for its own use, for example its firmware is often on the drive for some make/models, and so is the bad blocks map. If this sector isn't reading correctly *who knows* what weird things that could trigger. I know who, the person who writes drive firmware. I don't, so I can only speculate that this looks pretty much like a drive that needs to be used for some other purpose or disposed of. And also? Maybe it's getting worse. Maybe it wasn't exhibiting any of these problems yet when you were using NTFS and ext4. Or wasn't ever detected. The first thing that did detect it was LVM thin's metadata checksumming. And the most recent is btrfs. If it were in warranty I'd say make it the manufacturers problem. If it's not, well you could take a chance with it in a Btrfs raid1 with some other cheap drive. Whatever problems they have will be different, and Btrfs will automatically detect and repair them as long as they don't happen at the same time in the same place (astronomically unlikely). So that'd be a good use for it. I personally wouldn't be any other file system on it except maybe ZFS, because with this behavior, you don't want to trust any data to it without full data checksumming.

All low level stuff is like this, yeah. -- Chris Murphy _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
