Thanks a lot, Nick; that is very helpful. I just have two more questions:
I think I should use LVM for the remaining space on the SSD (which is where I am mounting /) and for the HDD so I can mount flexshares on the HDD. Is this right?
Also: I was trying to use encryption but if you use encryption does that mean you have to have a keyboard and monitor plugged in when rebooting so you can enter the password?
I have an HP Microserver Gen10, a 256GB Samsung 860 Pro SSD and two WD Red 6TB HDD and I am not sure how I should and do set up the mounting and partitioning.
Obviously I intend to boot from the SSD so I put "/boot" on there at 500MiB which I got from the automatic partitioning, and I want "/home" and "/var/flexshare/shares" to go on the HDD in a level 1 RAID.
I am not sure about the rest.
Apparently the swap partition should be the same size as the amount of RAM but it doesn't like that exact amount so I guess I should go for a little bit more. Is this alright?
On the location of the swap partition: should I put it on the SSD or the HDD? I would put it on the SSD but I am aware SSD have a limited amount of writing that can be done to them so I was thinking HDD.
Regarding the level 1 RAID: should I use software RAID or hardware RAID?
What is the /store/data0 directory and where should it go? It is mentioned briefly on the Configuring Partitions and RAID page but not much is said about it.
Do I need to specify an amount of storage space for all partitions other than "/"? It is a bit difficult to predict how much will be required for the "/home" and "/var/flexshare/shares" directories so I would like them to share the same space. Perhaps I should specify lots of other directories on the SSD and put the "/" partition on the RAID. What do you reckon?
Apologies for the amount of questions.
Help would be greatly appreciated.
Thank you very much for your help.
"chmod -R 774 *" worked.
In case it matters: the owner of the contents of the troublesome directory is "anon".
Any idea why this problem would have occurred and how to avoid in in the future?
