Could this mean that my SSD dies?
Might be, but first try replacing the cable. I really do hope SSDs last longer than four years, unless it runs full time.
uptime 6000 hours. I did a smartctl -t short which showed no errors then I saw that smartctl tells me that tomshardware/crucial suggests a firmware update because some of those drives are known to hang every hour after 5000 hours uptime. However, then my ssd would be 1000 hours late with this known bug. I updated the firmware nevertheless AND also changed the cable - why not. Now I will have to wait if the error comes back.
And where is the output of Strg+Alt+F10 stored?
In the system log, /if/ the system doesn't crash before it can write to the disk.
my system log seems to be non-persistend. however I grabbed pen and paper when it showed up some minutes ago. There are many repeating lines with this: "date+time kernel: [long-number] blk_update_request: I/O error /dev/sdb2 sector $changing-number" sdb2 is root, ext4, SSD, latest TW x64
I can´t find the i/o error messages in /var/log/messages, dmesg, xsession-errors or boot.log. Are there other important log-files I missed?
dmesg would show everything, if the system is still running after the crash. boot.log would show nothing. "/var/log/messages" should have the same as dmesg shows, /if/ it is enabled, because in 13.2 it is not. Instead, you have to query "journalctl".
Which diag program do you use to check your SSD with mounted root?
smartctl :-) See the man page, it has examples.
The test runs while the system runs, in the disk hardware, without involving the system cpu. When it finishes, you just use "smartctl -a /dev/sdX" to query the result.
I don't use SSD, but rotating disks, so there will be differences in the output. There should be a life estimation.
