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.

Hi Craig, 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?

Re: Boot problems after adding 2 new disks
Hi Craig, Thanks for the advice, I cleared the partition tables and eventually worked out how to create new partitions and set the filesystems up. For me the partitioning tool in Ubuntu is a quantum leap behind the partition manager in Mandrake/Mandriva, it is a pity that that graphical partition manager was not used universally. I am grateful for the assistance because now I have a system running, but it is running from a tty. I ran the command startx to get a graphical screen up, the system suggested an install of xinit, and that is loading at present. Unfortunately I am stuck in tty1, I thought that the GUI was on tty7, but I have forgotten how to get there. I thought it used to be CTRL ALT F7 I have a system, now, but not usable by me at this stage.

Nice CPUs for their day, and still pretty good even today. most of my machines have these. If you have an FX CPU, they're happiest with DDR3-1866 RAM. DDR3 is slowly disappearing from the market so you have to get what's available - other speeds will work if you can't get 1866, but 1866 is optimal.

It really depends on whether you want to upgrade every 6 to 12 months (18.10), or every two years (LTS). Stuff like gimp and darkroom tend to be fairly fast moving, so upgrading them every six months or so is probably a good idea. I'm generally in favour of keeping systems upgraded regularly. IMO two years is two long between upgrades. Free Software development moves way too fast for that. craig PS: what kind of GPU do you have? if you do a lot of graphical work, it may be worthwhile comparing some of the current low-end to mid-range models to your current card. A modern $200-$300 GPU should be 2 to 3 times faster than, e.g., a high-end GPU from 5 years ago, and use significantly less power. but this is definitely something that needs significant research before buying anything. googling "old model name vs new model name" gets good results. e.g. "gtx-560 vs gtx-1050" leads to several review sites which say that the 1050 (~ $170) is roughly 87% (1.87x) faster than the 560, and uses only 75 Watts rather than 150 W. The next model up, a "1050 Ti" is a bit over twice as fast and costs about $200, also using 75W. and the GTX-1060 3GB model is about 3.65 times as fast as a GTX-560 and costs about $250 (using 120 W) BTW, "2-3 times as fast as what I currently have for $200-$300" is generally what I wait for when upgrading my GPU. Unless noise and power usage is a problem, it's not really worth the cost of upgrading for anything less. Sometimes, though, new features of newer cards (like better video decoding or newer opengl/vulkan) makes it worth upgrading earlier. There are various AMD Radeon models of simialar performance and price. Unless you're willing to use the proprietary nvidia driver, you're better off with an AMD GPU. their open source driver is much better than the open source nouveau driver for nvidia. I mostly use nvidia cards with the proprietary nvidia driver (the AMD fglrx driver always sucked and the open source drivers for both amd and nvidia used to suck. now they're kind of decent, especially the AMD driver, unless you do a lot of 3D gaming at 1440p or better with all the pretty turned up to Ultra) -- craig sanders ___ luv-main mailing list luv-main@luv.asn.au https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main

Sooner if you help. 1 I knew, but I am glad for some idea of the time frame. 2 I would like to, but probably documentation, but I am still on the steep part of the learning curve, along with my paid work leaving me somewhat flat as an understatement. > Some would add, and in fact have been known to print on t-shirts: > > 3. Debian: Even hell freezes faster. Depends on what you believe about hell. Some would argue that we are already there but do not recognize. For me, doing the same thing day after day for eternity does not look quite so much to look forward to. I take the attitude that when I choose to stop learning, I will be choosing to put myself in my grave. The trouble is that it takes more to learn whatever I want and whatever the motivation, and I definitely still want to learn.

Re: Boot problems after adding 2 new disks
If you have a RAID-1 of 2TB disks a single 1TB disk doesn't provide much value. I suggest using the port for a second SSD instead and have a RAID-1 on SSD for root and /home and 2*2TB RAID-1 for everything else. If a 2TB RAID-1 isn't enough for your big files then consider getting a couple of 6TB disks, they are cheap nowadays. -- Sent from my Huawei Mate 9 with K-9 Mail. ___ luv-main mailing list luv-main@luv.asn.au https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main
