Syslog was full of balance_pgdat erors (still not sure what those mean, and whether they are critical), so I couldn’t see any entries related to hotplug events. Can you do this?
remove SD card
ssh into the device
run tail -f /var/log/syslog | tee hotplug.txt
plug the card in
wailt for the hotplugging to finish either with error or success
extract hotplug.txt from your device and post it online
It is possible that ext4 filesystem you are creating is not compatible with the kernel. We’ve experimented with ext4 using latest Arch Linux, but it’s possible that some distros use weird defaults that result in incompatibilities. IIRC, LH includes mkfs.ext4 command, so perhaps using that to format your card will give better results.
No, it’s more about the default ext4 options that are specified by the OS. I’m not sure what the defaults are on LH, though. I can look it up if you want.
the old sd was formated on ubuntu 15
the old sd was working on 1.4.3000
on the 2.0.000 the old sd do not apear on storage devices…
the new sd was formated on the LH , but do not work or the LH do not detect this sd
now, im on the old sd, the LH its doing som check ?
