You might be best recreating the array and restoring from a backup. Since the controller doesn't know about your file system, I can't see how it would know what parts of the array are in use vs not in use.
I don't see why the file system would matter, RAID is below the file system.
14 hours is not horrible depending on if you are using the system live or not. However if the array was larger the rebuild would have to read more data. Not sure how much slower this makes things as it should be able...
Yeah I'm trying to be backup-first before worrying about the raid. It's not like the raid will protect me from theft or other damage to the system (including from software).
But I don't want to restore from a backup every 6 months if a drive fails as it can be a bit of a pain. Otherwise I...
No I am talking about raid 1+0. As the number of drives increases, there are more chances that a drive will fail. However there are also more possibilities for the failure to be in a place where it does not take down the array. These probabilities cancel each other out.
Anyway my original...
With RAID 10, the odds of a disk failure taking out the array is the same as RAID 1. It does not increase as the # of disks increases. With RAID 6 this is not true and that should be considered as well.
Not to mention how URE affects a RAID 6 rebuild.
ZFS is not really an option for me...
Seems like it is about the RAID size rather than the number of drives? During a rebuild, all data must be read in order to reconstruct the data. Whereas with RAID 10, only data from one drive needs to be read which is a big win.
I make three copies to LTO-6 and store them offsite.
But like others have said, I'm leaning RAID 10 for safety reasons. The data is video footage that is written one time and read many times. I'm also considering the new SMR drives.
I'm thinking about a 12x6 TB RAID 6 resulting in 60 TB total using HGST NAS drives. However due to the higher URE rating on these drives compared to enterprise drives,I'm concerned about failure during rebuild.
Has anybody tried such a configuration and done some rebuilds?
How is their tech support? I am trying to decide between Areca and Adaptec. I have contacted Areca with some questions and never received a response. Adaptec has been very good with responding, which is a big plus.
The main thing I like about the 1883 is how the ports are laid out coming...
I'm curious as to why you chose these drives? With a 6 drive Raid6 you have:
32TB at ~$4800
You could also do:
10 x WD RE 4TB = $2800, faster rebuild times, higher performance reads
16 x WD Red Pro 4TB = $3680, faster rebuild times, higher performance, higher safety
I am intrigued by the 8Tb...
Newegg has them for $299
The 1883-ix-24 is available on ArecaDirect now. Trying to decide between this and the Adaptec Series 8 + Expander.
-Expander is on the same card
-More DRAM cache
-Twice as many native ports
-SSD cache available (although drives with enough endurance for this are out of...
No, I didn't think that worked for pixels that wouldn't turn on? This is a green pixel that won't come on, which makes it really obvious with white backgrounds and such.
I can give a pixel fixer a try...
Got the display hooked up. It looks nice. I see the AG in my movies but it isn't horrible.
However I have a dead pixel which is pretty annoying. Does anybody else have one? I'm thinking of asking for an exchange.
Yeah. I wish I had a handle on how bad the mouse cursor will be at 30hz under Windows. The closest I can try is 24hz with my projector and it is a bit painful.
I know that turning off Aero helps some, but that is not practical for me since I edit video and don't want tearing.
I'm used to a glossy screen. Unfortunately my Shimian just died and I'm temporarily using a Dell 2410 as a backup. The AG coating on this screen his horrible! How is it with the AOC? I can control my lighting so gloss wasn't a problem. However I'm having a tough time finding a good glossy...
