dougnliz Posted March 17, 2017 Share Posted March 17, 2017 Hi folks, Suddenly today I am not able to copy large files to my array. I don't see any issues on the dashboard, but when I copy to a Share it starts fine, but the speeds slows way down and eventually fails. I tried copying to the Cache drive and that works just fine. Enclosed are my diagnostics. Any ideas what's going on? Thanks, Doug tower-diagnostics-20170316-1951.zip Quote Link to comment
dougnliz Posted March 17, 2017 Author Share Posted March 17, 2017 I rebooted and ran a fresh set of diagnostics in case there is anything at startup that might be helpful. No change to the behavior after reboot. tower-diagnostics-20170316-2017.zip Quote Link to comment
dougnliz Posted March 17, 2017 Author Share Posted March 17, 2017 So I was able to copy the file from the cache disk to the array using midnight commander. It seemed quite slow but was successful. It said it was copying around 33 MB/s. Quote Link to comment

There are actually 2 different ways to configure writing with parity. Quote Link to comment

When I try to copy from Windows to the Array it's still failing though. The copy starts okay, but then trails off to nothing and eventually fails. 1 Quote Link to comment
dougnliz Posted March 17, 2017 Author Share Posted March 17, 2017 I was still running version 6.1.9 so I decided to give the upgrade a try. The upgrade to 6.3.2 went smooth and everything seems to be working okay. I tried the copy from Windows again and this time it succeeded. It's still a bit odd though as the copy speed fluctuates from 100+ MB/s down to < 1 MB/s. It stalled a few times but ultimately didn't fail though which is good. Are these wide speed fluctuations normal now? Doug Quote Link to comment

Quite normal with reiserfs, you already have some xfs disks, enable disk shares (if disable) and copy to one of them, eg, \\tower\disk9, do you see the same behavior? Quote Link to comment
dougnliz Posted March 17, 2017 Author Share Posted March 17, 2017 Ah I was just considering taking on the conversion from reiser to XFS. Maybe it's finally time.Sent from my SM-N920V using Tapatalk Quote Link to comment
