SOLVED - Scanning for Btrfs - slow Bootup - started today

Post by bill_steamshovel » Sun Oct 21, 2018 7:32 am

Hello,

Linux Mint 18.3 Cinnamon has been running very well for a couple of months now.

Today it took 10 minutes to boot, I rebooted three times in a row, and gave me these messages

Scanning for Btrfs file systems (- this line displayed once only)
[Numbers in square brackets ie 552.720805] Buffer I/O error on dev sr0 logical block 0 async page read
blk update request I/O error, dev sr0, sector 4

this goes on for at least 600 seconds if the numbers in the square brackets are some sort of clock, seems to take about 3 seconds to go through the cycle and display the next message on the screen, the block numbers and sector numbers go up with each iteration of the cycle

I did find a thread regarding bootup and btrfs on this forum but didn't understand much of it

Any tips or suggested readings please ? EDIT - inxiFxzd.odt attached below but it says "not downloaded yet"

EDIT - possible solved - had a CD in the slot and it may have been trying to boot from a video dvd

sudo apt-get remove btrfs-tools && sudo update-initramfs -uk all

Btw, your 4.10.x kernel version is long time now unsupported.

Think I get it

not downloaded yet means nobody had downloaded it not that it hasn't been sent from my PC to the Forum which is what I always assumed, this always puzzled me.

oh yeah ..... and it was the dodgy ruined dvd that caused the bootup problem.

Thx - thanks - will investigate updating the kernel with the update manager - being a learner, have always been quite wary of that and have avoided doing it.

...indeed, my fault for reading the above too quickly,
blk update request I/O error, dev sr0, sector 4 was a dead give-away, not a btrfs issue.

You can always simply copy/paste the inxi -Fxz output from the terminal here as well instead of .odt files by the way.
