Very happy vegemite atm, I disconnected my optical drive so I could hook
up my old SATA HDD. Well, it was found by the system and automounted. I
was getting ready for a mount operation. No Need. I am loading my SSD at
present and then I will put a bit of data in the /Data directory to see
how the balancing deal goes. When that is OK I will just dump the rest
of the data.
Thank you very much.
Truly grateful
Andrew

Referring to an earlier message about my data drives, do I need to CHOWN
those drives to andrew:andrew and then set the permissions to rwx?
I think i said perms should be 664. that was wrong. the execute bit is needed
to access a directory, so it should be 775 (rwxrwxr-x).
770 (rwxrwx---) would also work if you didn't want any other accounts on the
system (other than root and andrew, and any accounts that you add to group
andrew) to access it.
the chown and chmod commands need to be run so that your user is able to read
and write to the /data directory. Otherwise it'll be owned by root and only
writable by root.
NOTE: the chown and chmod need to be done while /data is mounted. This only
needs to be done once, and will retain the owner & permissions metadata
whenever it is remounted (e.g. on a reboot).
if you do the chown & chmod while the /data fs isn't mounted, you'll only
be changing the permissions of the empty mount-point directory, not of the
filesystem.
I think you mentioned a symlink, would that be necessary if I have done the
CHOWN?
the symlink was for convenience only. useful but not necessary. mostly so that
you can just navigate to your home dir and double-click on the symlink in any
GUI file chooser dialog. or from the command line "cd ~/data".
How do I set up the RAID1 on the Data0 and Data1 drives, please?
see my previous message. you should have only a /data fs combining
both the 2TB drives into a single btrfs raid1 array.
I have btrfs on all drives. I am amazed at the speed of an SSD.
Yeah, they're bloody fast, aren't they? and NVME SSDs are even faster.
I will pick up the RAM and a cradle for the SSD as it does not fit anywhere
in my case. It is just sitting in there at present.
There are no moving parts in an SSD, so it's safe to leave it just hanging
loose indefinitely until you get a cradle for it. I wouldn't do that for a
HDD except in some of data-recovery emergency, but it's not a problem for an
SSD.
