Hi team, I've had a 7-disk RAID-5 system running for months on a 2.6 kernel it it's been great. I had a need to expand, so I bought 4 more disks and I'd expanding using raidreconf from: http://unthought.net/raidreconf/ I saw the warnings and - you guesses it - it's happened. My reconf is going very slowly because I keep getting write problems (however it does *slowly* advance in progress) on 4 of my 11 disks. The 4 disks in question are all on the same SATA controller. Some notes to point out: - I ran a test expansion of 4 /dev/loop[0-4] to /dev/loop[0-8] RAID-5 and it worked, so my steps *should* work - I ran SMARTCTL checks on all disks before doing this, all was clean - I copied over 1TB of data to or from all these disks before I started, so this seems to be a net-new since I started raidreconf - All the errors are coming from the same 4 disks which are on the same controller. - I'm still running raidreconf because if I stop it, I will lose everything I know I took on this risk when I started my conversion. But I'd like to get any pointers I can since my honeymoon photos are on there (sentimental value is priceless - insert divorce comments now). Here are my questions: - Is there something I should be looking out for that may suddenly cause these errors to show up (static, improper grounding points on the disk drives? anything?) - Now that I'm seeing these messages show up every 5 sec or so, how can I reduce their frequency so it will not take 5 years to finish this expansion. Any help would be hugely appreciated.
