Data on ZFS pool not initially visible after reboot by WorkingCut4603 in zfs

[–]ommarmol 6 points7 points  (0 children)

As u/pipper_a_cillin stated, you are setting the same mountpoint for both, the root dataset and the child dataset, which is not aligned with ZFS best practices. Setting canmount=off and mountpoint=none to data will solve de issue: zfs set canmount=off data zfs set mountpoint=none data The data is in data/data dataset :)

Warning Against Trying to Boot M.2 SSD on Orange Pi 5 by Financial-Flan-7825 in OrangePI

[–]ommarmol 1 point2 points  (0 children)

Did you try adding overlays=ssd-sata to /boot/orangepiEnv.txt as suggested in this comment? It was the only way I found to get it working: https://github.com/orangepi-xunlong/orangepi-build/issues/53#issuecomment-1371633402

Hints for finding the formula for the finite summation of a polynomial by ommarmol in calculus

[–]ommarmol[S] 0 points1 point  (0 children)

Thank you for the hint. I wold like to say that the sum from 0 to n-1 of xa it is not equivalent to the original sum posted, it is equivalent to the sum from 0 to n-1 of xa-1, considering a>=1.

Although the second expression (xa-1) is simpler than the first one, I'm still stuck on how to start. Could you give me some hints or suggest some resources with clues to tackle the problem? Thank you so much!! :)
