I chose to close as a dup. My reasoning was this:
1/ The question asks "What is the purpose of this folder, and is it okay to delete the files and folders under it, or not?"
2/ The dup answers the first part of the question "What is the purpose of this folder" and allows the OP to make his own decision of the second part of the question.
3/ The OP doesn't provide enough information to answer the second part of the question "is it okay to delete the files and folders under it"
4/ That makes this bit _too broad_ **and** _opinion based_ - we don't know what software he has installed that is us…

omfg work is just bonkers

/me is now on lunch thank god.

For one client we normally only cover out of hours, business crit stuff

for some reason we are covering for their normal helpdesk for a week

so we have nothing on anything not business crit. told it'd be like 12-15 tickets a day

in 3 hours, we had over 20

@DavidPostill Step #2: "The dup answers the first part of the question [~snip~]". That's where I disagree.

How can you disagree with
> Roaming is the folder that would be synchronized with a server if you logged into a domain with a roaming profile (enabling you to log into any computer in a domain and access your favorites, documents, etc. Firefox stores its information here, so you could even have the same bookmarks between computers with a roaming profile.

and
> Roaming. This folder (%appdata%) contains data that can move with your user profile from PC to PC—like when you’re on a domain—because this data has the ability to sync with a server. For example, if you sign in to a different PC on a domain, your web browser favorites or bookmarks will be available.

?

Two explanations of the purpose of the folder.

user226528

@DavidPostill It is not the purpose of the folder. It is what happens to it. In other words, the question would become "What is the purpose of these files that bother to move from computer to computer and is it safe to delete them?"

I think I told you about elusive answering already.

DavidPostill

And I disagreed with you last time.

user226528

Like your elusive answers, this answer contains zero data. ;) Because there is no known record of you and me agreeing.

DavidPostill

The purpose is what it is for. That question is answered. Let us agree to disagree :)

user226528

Actually, it is you who brought it up in the first place. I have not been showing any signs of not agreeing to disagree.

user226528

So, as long as you are good, I am good.

I'm confused

are you arguing that the linked question isn't a dupe?

bertieb

Is the thing about it being potentially tricky to expand zfs storage (cf 'hidden cost') true?

djsmiley2k

'is it safe to delete these files, what are they' ?

'no, and they are...' is in the dupe answer... soooo

user226528

@djsmiley2k Not me.

bertieb

(I am swithering between mdadm (raid6) + lvm vs zfs + raidz2)

DavidPostill

@FleetCommand Actually I brought it up here because:

@Run5k All your comment did was to add fright to my pain because now I am thinking these high-time close voters could have committed many other mistakes. Many, many, many, many, many, many, many ... other mistakes. — Fleet Command 2 hours ago

bertieb

10:16 AM

I would ask a question, but having difficulty is phrasing such that it's not opinion-based or learning-recs

djsmiley2k

@Run5k I don't think this question is a duplicate. The other question asks what the difference between "Roaming" and "Local". This one asks what is their purpose. — Fleet Command yesterday

it explains what they are, because of their purpose.

user226528

@DavidPostill Oh, yeah? My discussion with Run5k was over meritocracy. That duplicate flag ceased to be relevant.

djsmiley2k

@bertieb start 'How do I...'

user226528

@djsmiley2k Yeah. Pretty much. But that discussion ended. At least in my book.

djsmiley2k

@FleetCommand hmmm

if they are all bad, then everything is bad

bertieb

10:18 AM

@djsmiley2k 'How do I...' '...decide whether to use zfs or madam + lvm' ? :P

djsmiley2k

so you might as well give up now

@bertieb ah i see

user226528

@djsmiley2k Give up on what?

djsmiley2k

how do i setup x with LVM+MDADM

@FleetCommand fighting whatever fight you seem to think matters.

bertieb

I've done the lvm + mdadm setup for a Xen dom0 (host) before so could just go with that; but zfs seems like it has decent merits too.

OTOH if zfs is less flexible about adding drives to a tank/pool (terminology??) it might be less attractive

djsmiley2k

@bertieb I've never used zfs, tho I knew the guy who was working hard on getting it stable on linux

bertieb

10:21 AM

(basically I have 4 pristine 3TB drives waiting to go, but another couple of non-pristine 3TB drives, the data on which will be migrated to the array-- would like to then add those 3TBs to the original 4, y'see)

djsmiley2k

tbh i guess if you can't find a way to phase the question for the site, then it's not suitable?

bertieb

@djsmiley2k Ah, fair enough

djsmiley2k

'How would I plan a ZFS build for expansion in the future?'

and if the answer is 'you don't', then you know to use mdadm instead F:

bertieb

Heh

djsmiley2k

Why are you using LVM + mdadm??

bertieb

10:22 AM

That seems like a reasonable start; I did wonder about it being too broad tho?

djsmiley2k

Describe your specific setup

bertieb

Me? Or another example of a response to that question?

djsmiley2k

Yeah you

I used to use mdadm, now I use lvm instead

not both.

So i'm interested in what you're doing

bertieb

mdadm for raid6, lvm for volume management

djsmiley2k

why not use lvm for the raid?

Q: Expanding RAID6 with LVM

My question is a bit broader than the question title, but here is my situation: I have Synology Hybrid Raid (SHR) built on 2 x 2TB drives. I want to migrate to a software-RAID on a homegrown linux machine. My current plan is backup the SHR remotely, setup a RAID6 with LVM using 3 x 2TB drives, an...

bertieb

10:25 AM

Heh, just reading that Q in another window ;P

What would be the reason to not just use mdadm to create/expand/manage the RAID? — soundsofpolaris Jan 28 '14 at 20:16

Q: RAIDing with LVM vs MDRAID - pros and cons?

In his answer to the question "mixed raid types", HBruijn suggests using LVM to implement RAID vs the more standard MDRAID. After a little investigation, it seems LVM also supports RAID functionality. In the past, I have used LVM on top of MDRAID, and was not aware till now that LVM also suppor...

lvm raid software-raid md

(a few years old now, right enough)

djsmiley2k

yeah already looked at that

bertieb

Anyhoo, good to know lvm-raid is an option; that said, I'm comfortable with mdadm and lvm and it seems like a nice unixy 'separation of responsibilities'

djsmiley2k

yah true

it looks like lvm just uses mdadm raid under neath anyway :D

bertieb

Ja

@FleetCommand Imo if the question being "wrongfully closed" can be mistaken for a rightful close, then it isn't good enough and may be closed. Also for 5 dumb people voting to close in 4 days if there's more than 100 views or 14 days if there's less is pretty hard to get. and if you think it's illegitimate, you can ask for a reopen in meta/chat.
