https://bugzilla.suse.com/show_bug.cgi?id=1218925 https://bugzilla.suse.com/show_bug.cgi?id=1218925#c14 --- Comment #14 from Daniel Wagner <daniel.wagner@suse.com> --- It turns out kernel 5.14.21-150500.55.39-default ships all the patches which allow duplicate nsids for pci devices which do not expose set the cmic or nmic bits (these are the patches I was referring to in comment#2). The id-ctrl and id-ns output show that these fields are not set. As all these condition are meet the nsid quirks is enabled automatically. This matches with the statement from the initial comment that the kernel says 'duplicate nsid' and warns from 'possible data corruption' (if you see these message the nsid quirk is activated). That means there is no need to set the nsid quirk by hand. BUT as the warning says, this quirk can lead to data corruption. The issue is that the /dev/disk/by-id symlinks are not stable. How do you address the disks in /etc/fstab? -- You are receiving this mail because: You are on the CC list for the bug.
