[02:28] <faekjarz> Hi! I'm installing 20.04 onto 2 md-mirrored USB sticks, setup finishes, reboot, and the array is degraded - lsusb lists only 1, not both sticks. What happened - any ideas?
[02:30] <sarnold> faekjarz: is there anything in dmesg thatmight describe it?
[02:31] <faekjarz> sarnold: when, after the 1st reboot, directly after setup?
[02:32] <sarnold> faekjarz: yeah, or perhaps if you can compare the before and after, to see what's changed..
[02:42] <faekjarz> interesting idea - i'd have to nuke and pave under enhanced experiment conditions. that's what i'll try next. while i'm at it i'll not simply reboot the server, but power-cycle/hard-reset it. if it's the mobo/uefi buggering the USB enumeration during soft-reboot, that should be a completely different 2nd variable. this will take a while ;)
[02:47] <faekjarz> btw, i followed this md-raid guide https://askubuntu.com/questions/1234949/install-ubuntu-20-04-focal-fossa-with-raid-1-on-two-devices#1247308
[03:52] <faekjarz> is it possible to create an md-mirror with only 1 member / can i create a mirror into a degraded state?
[05:09] <faekjarz> sarnold: i think i've identified the issue - faulty USB sticks (unrecoverable bad blocks)
[07:48] <lordievader> Good morning
