Re: Recommendation on raid5 drive error resolution

Things have been copying off really well. I'm starting to suspect the issue was the PSU which I've swapped out. What is the line I should see in dmesg if the degraded option was actually used when mounting the file system? On Thu, Sep 1, 2016 at 9:25 PM, Austin S. Hemmelgarn

Or I could just once again select the right boot device in the bios. I think I want some new hardware :) On Wed, Aug 31, 2016 at 7:23 AM, Gareth Pye wrote: > On Wed, Aug 31, 2016 at 4:28 AM, Chris Murphy wrote: >> But I'd try a newer kernel before

Am I right that the wr: 0 means that the disks should at least be in a nice consistent state? I know that overlapping read fails can still cause everything to fail. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More

Re: Recommendation on raid5 drive error resolution

Current status: Knowing things were bad I did set the scterc values sanely, but the box was getting less stable so I thought a reboot was a good idea. That reboot failed to mount the partition at all and eveything triggered my 'is this a psu issue' sense so I've left the box off till I've got

Re: Recommendation on raid5 drive error resolution

Hi Gareth, I'm interested in how you go with this as I'm somewhat similar with RAID5 with both. Don't take this as advice as I have never done it; however if I were in your shoes, I would take out one of the disks that isn't playing nicely and rebuild the array. Once it is running smooth

So I've been living on the reckless-side (meta RAID6, data RAID5) and I have a drive or two that isn't playing nicely any more. dmesg of the system running for a few minutes: http://pastebin.com/9pHBRQVe Everything of value is backed up, but I'd rather keep data than download it all again. When
