After I first installed my Helios64, I feared the 16Gb eMMC would be quickly filled.
So when I used nand-sata-install, I chose to boot from eMMC but to have the root filesystem on a 500Gb sata drive.
I have now second thoughts about it, since I realized that the OS take less than 8Gb, AND I'd like to add a 5th disk to my raid
Halas nand-sata-install doesn't seem to work on an already moved filsystem.
lsblk show this for the eMMC and the root partition
peyo@helios64:~$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 465,8G 0 disk
└─sda1 8:1 0 465,8G 0 part /
...
mmcblk2 179:0 0 14,6G 0 disk
└─mmcblk2p1 179:1 0 14,4G 0 part /media/mmcboot
And /etc/fstab shows this
UUID=f2d7d6e7-902c-44dc-bdae-aedeb4495385 /media/mmcboot ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro,x-gvfs-hide 0 1
/media/mmcboot/boot /boot none bind 0 0
UUID=0fcd9a2c-9a46-4a5e-a0f5-e407bd34e8fb / ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro,x-gvfs-hide 0 1
...
And in /media I have this
peyo@helios64:~$ ll /media/
total 8
drwxr-xr-x 3 root root 4096 déc. 6 11:31 mmcboot
drwxr-xr-x 2 root root 4096 déc. 6 11:31 mmcroot
Would it be so simple as
1 - rsync all that's on my present / (except for the NFS export and /tmp)?
2 - changin /etc/fstab to this
UUID=f2d7d6e7-902c-44dc-bdae-aedeb4495385 / ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro,x-gvfs-hide 0 1
3 - reboot (with crossed fingers)
