but my linux can’t connect file system of ssd. is it Encrypted? is it ext4 ? can’t find info in documentatjion .
How correctly connect it to another pc and read data?

This is probably what you are looking for. Caution: there be dragons!

If you are just migrating Bitcoin’s blockchain data to a new StartOS server, we have a more specific guide for that.

Thanks Rexter,
first guide was super, but i get
/dev/mapper/EMBASSY_NBMVE7OASAPTIIXNEPFN6PLAPJNT72F2XAVK43L2PGB6O2JRB35A-package–data is not valid LUKS device
so it should be updated.
it was inside btrfs format
did mount command “mount -t btrfs /dev/dm-1 /mnt/startos”
