    Dropping a drive

    Thank you Christopher, It could be that the rack power supply is failing. Anyway, thanks for the diagnostic. Yossi

    Will do. Thanks.

    Dropping a drive

    I am uploading everything under the "Service" folder. But still, if there was a problem with the VDS, shouldn't I see something in the event log ? And also, how do I force DP to see the drive short of rebooting ? Can I reset the driver ? I should remind you that I cannot restart the service - it hangs on stopping.

    Dropping a drive

    Thanks Drashna, I have no new dropouts since I massaged the drives and replaced the controller driver. The controller is a JMB362 on a Gigabyte GA-P55-UD6 MB. It's connected to a SiI3726 port multiplier. The 2 issues concerning me are : 1. There was no indication anywhere of a problem (eventlog, HD sentinel). Also the drive was accessible with no problems by the file system. 2. I could not make DP to see the drive again without rebooting (tried ofline/online, enable/disable in device manager)

    Dropping a drive

    Thanks, I don't have the scanner installed. I had some trouble with installing it and I left it as such... I think your advice refers to it. Anyway I have given the VIP treatment to my disks, set all of them to max performance and updated the controller driver, let's hope the voodoo will help. The strange thing is that I do have a competent disk monitor suite and it didn't complain, and also the event log doesn't show anything.

    Dropping a drive

    I have a drive that keeps dropping out of the pool every few days. When I see the alert, I look into Event Manager and there is no event whatsoever, HD sentinel shows nothing, the disk shows OK in the device tree and in disk manager. I can access the drive via the OS (Win 2008R2) with no issues. Thing is, the only way that works for me to reset the situation is a reboot. Not very convenient. The drive is a green 2TB Seagate ST2000DL003. It is connected via a port multiplier to an JMB SATA port on the MB. I have 14 other identical drives and 5 WD 4TB red drives, similarly connected with no
  7. Thank you Alex, This was a very clear explanation. Complex product. Just looks simple from the outside.
  8. Is there a simple method to know where DP keeps a specific file ? Say an application opens a file for write while that file is being moved by a rebalancer. What will happen ? Similarly, say a file is kept continuously open (i.e. a database file). Will it be rebalanced ? How ? What about duplication ?
  9. Hi Drasna, I'm happy that it was found worthwhile. Thanks, Yossi
  10. Hello Drashna, Thank you for your speedy and complete answers. Well, regarding the service hang, today I tried to shut it down and it was in "stopping" state for 45 minutes at which time I rebooted. While waiting, I have taken a dump of the process and uploaded to you. In the comments I mentioned "User:ytulpan" I really hope that rebooting the server with a pending service stop doesn't corrupt data... Regarding the original issue. I have turned on the "immediately balance flag", so, yes, DP starts balancing, but nevertheless fills the pool in a wrong way in my view. The fol
  11. OK, some news. Regarding the "hang", well, I can stare down the process into submission . While preparing the trace files for sending, I was just blankly staring at the services applet for some time and bam, the process moved from "stopping to "stopped". So I tried this a few more times and it worked every time ! In fact, immediately after reboot, the service stops doubleplusquick. It is only after quite some data moved that it is sluggish. In my case it takes around 7 min. to stop, after the "failed to stop service" popup appears. So, do you need the traces anymore. At what tim
  12. Thank you Chris, Well, the balancer is on the percentage setting, unless I am blind; there are other balancers present, but only those supplied by covecube. I attach screen prints of the balancer page and the drive situation. Regarding the service hang stuff, it will take me some time since if I try to stop the service I will have to reboot; I can't reboot in the next day or so. Regards, Yossi
  13. Hi all, I recently installed DP and I'm playing with it right now. Great product. I have around 50 TB of data on 25 drives, I'm now testing various configurations with a pool of 20 TB of fresh disks plus some other disks I've connected for testing. Since I'm using quite a lot of hardlinks I'm running the last beta version (2.1.0.541) with some bugs in this area corrected. At this point I don't test file duplication. I started to load data into the pool by the standard balancer, and at some point I installed the Disk space Equalizer plugin in order to change balance from absolute am
