Sorry, should have been more detailed in OP. I have never had a parity drive - poor planning and sheer stupidity on my part. The drive that failed was Disk 1 (of a 4 disk + 1 cache) array. I'm OK with the fact that the data on that disk is gone, it sucks but I'll get through it. Assuming the disk is dead / data gone - what I'm wondering is, what is the procedure to get the array back online eventually? I'm RMAing the disk - do I need to wait for the replacement to come before I can do anything? Or can I reconfigure to run with 3 disks and just expand again when the replacement drive comes? Ultimately, I'd like to get the array back online ASAP so I can get the parity drive in place and have that going. Can't get a Syslog rght now, but I will try to get one later tonight if you guys are interested.

Smash me in the face with a hammer I'm dumb. Like a true idiot I assumed I was immune from hardware failure, but now the time has come to reap what I have sown. I had a WD10EFRX (Red 1.0TB) fail on me 2 days ago. I don't think there's any way I can get get the data back. The drive won't even spin up, clicks of death with only power plugged in (verified on different machines). Interesting thing is that, when I have the drive installed in the unraid server, the server boots - but something is off. A Teamspeak 3 plugin will start (I'm able to connect to the server and use that application), but the web gui won't boot up. I can telnet in, but that's about it. SYSLOG shows that the drive is there, but encounters a number of errors, and the device won't even execute a SMART test. (Running 5.0rc12a if anyone's curious). Anyways - I'm RMAing the disk, but I'm trying to figure out how screwed I am in the meantime. My array obviously tells me there's a disk missing, so I can't start it. But what happens when I get a new disk? How can I get that disk running in the array? Will I be able to replace the drive, start the array, and just have a lot of missing files? Needless to say - I have a second drive coming as well that will be my parity, and my lesson has been learned. Thanks all.

Hey all, first time standing up a NAS, and wanted to shoot some questions to avoid shooting myself in the foot. I'm planning on pre-clearing the drives I have (as it's my understanding that parity will be more or less a bit jumbled without it). However, all the stuff with AF has be a bit confused. I currently have 4 drives: 1x WD FAEX 1TB (black) 1x WD FALS 1TB (black) 2x WD EFRX 1TB (red) The red drives are going to be the meat of this build - the blacks are mostly to tide me over until I can afford to buy some more, larger reds. In my disk settings on the web config, I have the default partition format set to MBR:4k Alligned. Running Beta 5-12. When I run the preclear script on any of the drives without a -a/-A switch, it tells me that the drive will not be 4k-alligned. Setting the -A switch says that the drive will be 4k aligned. For performance, do I want to use the -A switch on all the drives? Just a few of them? Will my drives be 'compatible'? Sorry for the newbish questions... I think I see the benefits of aligning on 4k, but am not fully grasping the concept yet!
