You are correct. The single card can handle both boxes. I have my two boxes running off of the same card. But having a backup card isn't bad. And you never know if you want to plugin another esata device in the future.

I had something similar. One day I woke up and couldn't write to any of the folders. Eventually I found out that one of the drives dropped off the pool and was disconnected. I didn't think to check the DP console as I could still see the pool. After reconnecting the drive (rebooting) it worked again.

Great news. Even though the current card is working now you won't be sorry with the Mediasonic card. Its been running great for me for years. I'm waiting for the probox to drop in price so I can add a second one to the card.

Yup. That is the correct card. The HP1-SS3. I just found my amazon receipts to confirm. Also I found the thread where Drashna mentions the chipset issue... take a look. http://community.covecube.com/index.php?/topic/965-issue-when-working-with-folders/?hl=mediasonic&do=findComment&comment=6254 Hopefully this helps you out. I've been running smooth since Jan of 2015 when I replaced the card.

I also have the Mediasonic Probox. I tried different cards and was having a number of issues similar to yours where the box would drop off under heavy load. Drashna recommended a card based on the chipset a few years ago and ever since I got it it has been working flawlessly. I'm actually looking for a second probox to add to my system now. I ended up getting the Mediasonic 2 Port External Sata card off of amazon for 20$ CDN (it had the recommended chipset). I tried to find the threads where we discussed this but it was a number of years ago.

#2. I've done this a number of times. This is the thing I like about drivepool. On the new server install drivepool then just move all of the disks over and it will recognize the pool. The pool configuration data is stored on the disks.

Interesting. I have a very similar setup so now that I understand what you meant I can see how that is will be a pain. I guess logging a feature request with Crashplan would be a good option too so that they can incorporate a "only restore missing" option into their interface. I have about 1.5TB of data on Crashplan so I don't really want to switch. So far they have been pretty good but I have not had to do a large restore like that yet.

Good to know about the beta's. I just upgraded to the latest beta (from a previous beta) as I was having a few issues but didn't want to report anything until I have time to dig deeper.

Thanks for the links guys.. going to try it on the machine I'm having issues with as well. By the way Drashna the command line should have /t instead of /y in the above article.

If you look at crashplan you can set up the free version to backup up via lan or internet to another pc. this may accomplish what you are looking to do.

Yup. Mediasonic had the drivers for it. It port multiplication wouldn't work until it was installed. Working fine so far on Server 2012 R2 Essentials.

Just upgraded my setup to the Mediasonic esata card with the chipset you recommended. So far smooth. Pretty sure it will stay that way.

Yup. I tried that right after I got the logs and had the same results. Should I have rebooted after disabling the network io boost?

We are in luck. Was able to easily reproduce it. Just creating two text files ("new text document.txt" and "new text document (2).txt") on the share ("projects") and it wouldn't show up on the other computer. But browsing to the d: drive on the server they are there. Hopefully the logs show something. Let me know.

I do have network IO boost enabled. I will leave it enabled for now so I can grab some logs and hopefully duplicate the issue. This is a tricky one because it doesn't happen all the time, so replicating it will be hard. Let me see if I can do some tests to duplicate the problem and get the logs to you. May take me some time depending on how easy it will happen. Of course it happened this morning.

So doing a quick search for that chipset and I ended up on mediasonics page. They actually sell a 2 port card with that chipset on it. For 20$ I may just have to look into it and see if I can get ahold of it in Canada. I have another external box that works off esata without USB3 that I would like to use as well but always had issues with the dropping out. This will solve that issue as well. Thanks. On another note I've also run across another problem too. Not related to this issue. But wonder if you have seen it. If I have have two computers with explorer open to the same share and copy a file over to that share on one computer, sometimes it takes a really long time (10's of minutes or more) for that file to show up on the other computer. Even if I shutdown explorer and open it back up it still doesn't show. But if I go to a 3rd computer the file is there. Its almost like the cache or something is not updating. Does this sound like a drivepool thing or should I be looking at something else? PS.. if you want to start another thread let me know.

Excellent. So far it looks like it is working but I will report back in a few days once I have a chance to really try. As for the eSATA issue. I don't think its an issue with DrivePool. It was doing this when I was testing other products as well. I was able to troubleshoot and reduce the frequency of it going offline by disabling the link state power management. But when the enclosure was under really heavy load (like when scanner was running) it would still drop off randomly. I just switched over to usb3 and everything was working great so figured it was either the enclosure or the card. I was using the silicon image card for esata. From what I read that had issues.

I took a look in the event viewer and didn't see anything that stood out. When I had it on esata the entire box would randomly go offline for some reason so thats why I switched to usb3. Did anything show up in the logs i provided?

No. The 4 WD drives are sitting in a mediasonic probox that is connected via usb3. The ssd cache drive is plugged into the motherboard directly. I use to have them on esata via that card but it kept dropping out under heavy load.

Thanks again Drashna.

Hi Drashna, I have rebooted the server with nothing running and then recreated a problem. Captured the logs and uploaded them for you. Please contact me if you need any more details.

Ok, so I tried turning it on and no lock. Working with folders is still difficult. Moving, renaming, deleting all causes errors as if its still running behind.

Hi Lee, If you are talking about the indexing service I have confirmed that its not enabled on the server.

I have a strange problem and don't have any clue as to where to start. I'm running the latest version of drivepool (2.1.1.561) on Windows Server 2012 Essentials R2 with 4 WD Red drives and a SSD drive for the cache. When working with folders with a number of subfolders and files (via a network share or directly on the box) the folders seem to get locked and I am not able to delete them. It's almost like the pool is very slow to catch up. Sometimes I may reboot and they may unlock and let me delete them but sometimes I have to actually go to each drive and delete it directly from the pool parts. It only happens when I try to delete the top level folder. If I manually go through every sub directory and delete the files before deleting the folder they are in it works. But this is not practical. To help eliminate other programs that may be interfereing I started up the server with nothing running on it just to ensure it is still happening and it is. Any ideas as to where I can start troubleshooting this? Logs? Monitoring? Anything?
