Why is balancing so slow? Is it just me, or like this for everyone?I added two new 12 TB drives to my pool yesterday and hit Re-Balance, and it is taking forever. As you can see in the pictures, it is currently moving data from one of my 8 TB drives to one of my new 12 TB drives. It has been doing so all night at about 10 to 20 MBps. At this rate (2% completed in one day) it will take about 50 days. Also shown in the pictures is me bypassing DrivePool by manually moving some files within the PoolParts using Windows Explorer from a 10 TB drive to the other new 12 TB drive. Stablebit Scanner shows that these speeds are normal, around 200 MBps. They are all on the same HBA, so the problem can only be caused by DrivePool. I know the obvious solution would be to manually move all the files to the new drives myself like I demonstrated in the pictures, but that would still be several days of me babysitting the process. I paid for DrivePool, and would like to be able to use it so I can just hit the Balance button and walk away. I tried checking and unchecking the Bypass File System Filters and Network I/O Boost settings but that had no effect, and I am not using file duplication. Is there anything else I can try?
One Drive Business ExperiencesHi I'm after some experiences with OneDrive Business. After using Google Drive with no issues with speed, I'm not having a good upload experience. I have created 5x5TB drives using separate OneDrive Business accounts, all pooled with DrivePool using the DrivePool fixed placement plugin so each drive fills up one at a time. I have set the storage chunk size to 100mb. I have experimented with 2/5/10/20 threads and have seen the speed get upto 200mbps. Overall I'm lucky to see 6GB an hour of actual moved data to the cloud. Any ideas how to tweak, I have a 1TB cache and this is quickly filling and would take a week to move to the cloud if I stopped all of the transfers Thanks for reading.
Are the operations / IO / IOPS for Drivepool slower than a normal disk?
zurich posted a question in Nuts & BoltsIn Windows when deleting something like 100,000 files, it's quick and completes in a few seconds. This is a high-level delete operation. IO operations with Drivepool all take a much longer time than Windows. Things such as: In explorer: Right-click folder > properties (to view number of files, folders, size) OK, I'm not sure this one is drastically slower (if at all). Discovery takes a long time for a delete. Like #1 above. A delete operation take a long time for a large number of files. I'm talking like 50-150 IOPS, which makes me think this is related to disk IOPS. Can these operations be dependent on any settings for my pool, or is this just part of the territory for what Drivepool does beneath the surface? Correct if I'm wrong: operations in Drivepool seem to be limited by the IOPS of the disk(s) in question.
Poor Pool Performance - Ideas?Hey Guys - A couple of years ago, I started building my pool and have only added to it since. Currently, it's 32tb in total size which is comprised of 11 disks (one of which is an SSD for caching.) DrivePool has worked well for me and even though experiencing an issue, is much better than what I started with - DriveBender. My partition setup is like this: - C:\ - SSD - 256gb - OS & App Installs - D:\ - Drive Pool - 32tb - Storage (Mostly media) - E:\ - Hybrid - 1tb - Game Installations & VMs It seems as the pool has grown, it's performance has decreased. Initially, I thought it may be the OS so have tried complete OS reinstalls (not just restoring from backup) which didn't help. At the time, I had all of my disks plugged into the motherboard or one of two SATA expansion cards. After research and posting, I purchased a RocketRAID 2720 SAS card which had the ability to add 8 new SATA ports via 2 SAS->SATA fan out cables to bear some of the load. This seems to improve reliability and a bit of performance, but still not close to what the pool would be like compared to a single HDD. I do plan on reinstalling the OS again soon - but only because I do this 2-3 times a year anyways to keep things running at top notch. Issue Details Besides just slugish speed overall much of the time, most issues seem to be when I am reading files from a large folder, it takes a while - much longer than when I copied the folder to a similar single drive a while back. Also, when browsing through it in Explorer, sometimes it takes a while to display contents or if I delete files / folders, I must manually refresh to see the changes. The pool doesn't not contain the OS, paging, or any application installations. It's mostly used for storage of media, other various files, and is the download destination for many scripts. Individual Drive Benchmark To determine if the performance may be due to hardware or software, I set out today to run some tests. Using HD Tune Pro (5.60), I ran benchmarks on each disk in the system plus an external USB 3.0 for comparison. I only performed the "Read" benchmark as the "Write" one required wiping the disk. If there's a different type of test you suggest I run, please let me know. I had planned on using a different app, but was only able to select by partition - not disk - which obviously was an issue. I then recorded the results plus data gathered from StableBit Scanner + AIDA64 into a spreadsheet. The spreadsheet also includes a summary of my system specs as well as a couple of notes. Below is a screenshot of the report created today. If interested or easier to view, attached are copies in XLSX & PDF formats. I had to zip up the XLSX because the forum wouldn't allow me to attach it otherwise. Any ideas or suggestions? Thanks!!! Generalized Disk Benchmark Report.zip Generalized Disk Benchmark Report.pdf
Removing a drive is ridiculously slowI'm trying to remove a drive. I have 18TB with 5TB free and trying to remove a 3TB drive. I just added a new 3TB drive, so theoretically it could just copy files to the new drive and be done. Removing appeared to do absolutely nothing, thought it seemed to work fine when I tested Drive Pool in my VM's. I found much better results by using the Drive Usage Limited plugin and disabling the drive I wanted to remove. After rebalancing, the drive is empty except for a couple GB. Drive Pool reports no unduplicated files on the drive, so I know I could just pull it and let it rebuild later. Is there an issue with removing, or something I should know prior to removing? Rebalancing seems to be significantly slower than straight disk access too, but I figure that has to do with running the balancing rules and background priority. I don't mind mind the "maintenance" tasks being slow within the pool, as my speed to access the pool is still fine. At least i can see rebalancing working. I haven't seen the 2GB of duplicated files changed in the last couple hours of removal. I will let it run overnight and see what happens in the morning.
