Solved: Raid 5 Controller
I know nothing about RAID management, and though I have had no known problems after setting it up nearly 2 years ago and leaving it be, I would like to get So I ran dd in reverse on the disk I recovered using rmir back onto the original disk. The plan was to maximise disk space with parity and use RAID 5, should give me 1.9TB roughly. For some stupid reason, I've only got the choice of RAID 0, or solved Which RAID controller should I get for ESXi? http://bornsunsoft.com/solved-raid/solved-raid-0-uh-o.html
I had to buy a 2TB external drive to backup temporarily in preparation of this new setup, so I suppose I should just keep it plugged in and set an auto DistroUbuntu 16.04 Xenial Xerus Re: Advice recovering Hardware RAID 5 Originally Posted by rubylaser Are you unable to purchase the same card and import the array? marko55Jan 20, 2016, 6:24 PM First, you won't ever put your HDDs and SSDs in the same RAID set. It's good to hear it's automatic.
Then the parity distribution, left, sync. Its almost as if the card itself didn't fail permanently and neither did the drives (as far as I can tell). as it will also be a gaming PC(nothing too crazy) i would prefer the fastest and most protected, which is why i narrowed it down the 4(more like two really)so ive
If you want better help, post the exact RAID card model and chips here. Given this much data, how do you ensure that it is available all the time, that access times and throughput are reasonable, and that the data can be backed up and For example in some mp3s I get a length of the song, 2 seconds of another song, more of the first song, then another 2 seconds etc etc. Cheesemill Adv Reply August 6th, 2012 #5 MezzFA0 View Profile View Forum Posts Private Message 5 Cups of Ubuntu Join Date Jun 2010 Beans 20 Re: Advice recovering Hardware RAID

For instance, I'm working on a file server build that will have over 50 hard drives and we're looking at building multiple RAID-60 sets on multiple cards using enterprise hard drives. weblink This is where "write-back" comes in to play. Std Linux Sys Maint.. And my only options for pci-x were a few RAID cards.
Who would have though to check this when ordering. This is sort of a hot debate around the web as many people say that native "garbage collection" on the SSDs themselves does a good enough job, but that's not as Last edited by Cheesemill; August 4th, 2012 at 04:07 PM. navigate here But at least my raid is working until the replacement card arrives.
If you add one into optical drive you have to use conversion kit 3,5" to 5,25" and the drive will not be colled properly.This is the reason why any RAID 5 One way or the other, you always want your data from your RAID set backed up to some other drive or media, in a critical data environment anyway, which reduces the Write-back and RAID cache may keep you from ever noticing how "slow" your write speed is with RAID-6 though, especially if you don't do a lot of writing and even more
Sound like a lot?
That's interesting, how would that compare to the cheaper non-CPU RAID cards, performance wise? The biggest concern with parity RAID is losing drives DURING rebuild, after a drive has died in the array.

Sometimes the toughest thing with testing is if you build a super fast array, you have to have another array or disk in the same machine that's fast enough to test and kernel support it would be even better.
I haven't had the misfortune of having my card go out of me yet, but I am very diligent with my backups, so if it does go out, I won't be I then used RStudio to assemble a RAID5 and told it that disk x was missing. With that said, I haven't deployed a raid 5 configuration in about 6 years. Some things that could destroy your data in RAID 5 other than a spindle failure are A controller failure.
How does the O/S interact with the controller to deal with that issue, reconciling files (or directories) which are affected without having requested access to them first?
