October 8, 201312 yr If i create a file (say, 1024mb) and use scp to copy it to /mnt/user/Share/ it goes VERY slowly (down to under 1mb/sec over a 1gbit link) If i scp the same file to /mnt/cache/Share/ i get ~40mb/sec over the same link.. Now, am i wrong by copying to /mnt/user/* ? I thought this was meant to be the view of the array including cache, so all data copied to here should be added to the cache drive... I also get very slow copies using the GUI (in OSX) , so its not just scp having this issue. I have not, however, copied directly to the cache drive from the GUI.. perhaps I can try that, too. What am I doing wrong? Where should I be copying new data (so it ends up on the cache drive)
October 8, 201312 yr You are correct - writing to /mnt/user/Share should actually re-direct it to /mnt/cache/Share. Not sure why you are getting such slow speeds. It is normally slightly slower using /mnt/user/Share than writing directly to the cache (I presume because of re-direction overheads), but nothing like as slow as you are getting. Perhaps you should check your settings for the share to make sure it is specified that it should use the cache drive.
October 8, 201312 yr Author Yeah, I confirmed that the settings were ok before.. but just to be sure, I checked again. All shares are configured to use the cache disk. Im not too sure what is going on. Ive also had some other strange behaviour lately, and trying to update to 5.0 FINAL didn't work well either.. unRAID said it was on rc15 or something when I updated the files and booted it.. Is there a way I can backup my array/shares config and start from scratch?
October 8, 201312 yr Yeah, I confirmed that the settings were ok before.. but just to be sure, I checked again. All shares are configured to use the cache disk. Im not too sure what is going on. One other thing occurs to me - when writing to the /mnt/user/Share unRAID has to check the existing disks to see if the file already exists. Have you checked the syslog in case any disk is getting errors when trying to read it?
October 8, 201312 yr Author I know one of the controllers freaks out and complains about an IRQ issue.. This does slow down any drives connected to that controller, but not THAT much.. I do have an IBM M1015 on the way to rectify this problem. Perhaps I should wait until it arrives before taking more drastic action.
October 11, 201312 yr Author Its not a VM, its an Asus E35M1-M (AMD E-350) with 4Gb RAM Attached is the syslog, and the output from dmesg. Note the errors at the end of the dmesg output. syslog.txt dmesg.txt
