    License Reset

    in General

    Posted

    Good Morning, 

    I had to re-install windows on my computer that had Drivepool and Scanner installed. I sent a message to support through the website, asking for my licenses to get reset several days ago, however I have not heard anything back. Is it possible for anyone to check on the status for me.

     

    Thank You

     

    Any advantage to splitting among controllers

    in General

    Posted

    I have been running for a while now with no duplication, all 4 of my pooled disks on one pcie sata controller card and have replaced all 4 of the disks with larger disks and have enabled duplication. I was wondering if there is a performance advantage to splitting the drives across the separate pcie controller and the MB sata ports, (2 drives on separate 4 port sata card and 2 on the MB's sata card) ? 

    Not understanding the SSD Plugin

    in General

    Posted

    So today I added two 120GB SSD's to my system. I added them to my pool, selected them as SSD drives, turned off all of the other balancers, yet when I copy files to my drivepool, I can watch in the Drivepool interface, the files just copy to my archive drives and never even touch the SSD's?

    Update: I think I got this working, I had removed the drive letters from the drives in Disk Management and after giving them a drive letter , it seems to be working. I did have another question though, I dont like to have a lot of drive letter cluttering up my explorer, so I created a pool with the 2 ssd's and added them to my main pool, removed the drive letters from the individual drives so now the only drive that shows is the "pooled" ssd cache drives. I know I have read that you really should be using 2 ssd's for this to work well, and while I do have 2 ssd's , they now look like 1 to DrivePool. Will that matter?

     

     

     

    Anyone using the Snapraid runner powershell script?

    in General

    Posted

    So, i setup the snapraid-runner powershell script today, however I am getting a couple weird errors, and was hoping someone who has used this would have any idea how to fix it. First error is this, it still runs, just wondering what variable or whatever is not set to give me this error: Does anyone else use this, or have any idea what these errors mean?

    You cannot call a method on a null-valued expression.

    At D:\snapraidhelper\snapraid-helper.ps1:621 char:3

    + $config[$line[0]] = $line[1].TrimEnd()

    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo : InvalidOperation: (:) [], RuntimeException

    + FullyQualifiedErrorId : InvokeMethodOnNull

     

    Second is i/o errors on disks its trying to check, the disk throwing the errors is the actual Drivepool Volume, which it should not be checking, disk 9 in disk management is the actual pooled volume.

    Active code page: 65001

    Missing .covefs

    in General

    Posted

    I noticed during my first snapraid sync that i got the warnings about the .covefs directory on 3 out of my 4 drives, so I peeked into the poolpart directory that did not give a warning and noticed the hidden .covefs folder is missing, is this ok?

    Snapraid and poolpart directory

    in General

    Posted

    So I ran snapraid sync for the first time today, and i was a little troubled with the output, I thought the information in the poolpart directories is what is was supposed to be protecting, the output below seems to show its going to ignore those directories, does this look normal for a first sync? Also, not sure why it didn't ignore the special system poolpart directory on d3?

    Content Files

    in General

    Posted

    Just wondering if you can also put the content files in mount points, possibly the same drives you created mount points for the data disks? Like for example, would this work? In this example, the parity drive is its own drive, I am just mounting it to the same drive as the data drive mounts.

    # Example configuration for snapraid for Windows

    # Defines the file to use as parity storage
    # It must NOT be in a data disk
    # Format: "parity FILE [,FILE] ..."
    parity Q:\snapraidmounts\Parity\p1\snapraid.parity

    # Defines the files to use as additional parity storage.
    # If specified, they enable the multiple failures protection
    # from two to six level of parity.
    # To enable, uncomment one parity file for each level of extra
    # protection required. Start from 2-parity, and follow in order.
    # It must NOT be in a data disk
    # Format: "X-parity FILE [,FILE] ..."
    #2-parity F:\snapraid.2-parity
    #3-parity G:\snapraid.3-parity
    #4-parity H:\snapraid.4-parity
    #5-parity I:\snapraid.5-parity
    #6-parity J:\snapraid.6-parity

    # Defines the files to use as content list
    # You can use multiple specification to store more copies
    # You must have least one copy for each parity file plus one. Some more don't hurt
    # They can be in the disks used for data, parity or boot,
    # but each file must be in a different disk
    # Format: "content FILE"
    content Q:\snapraidmounts\Parity\p1\snapraid.content

    # Defines the data disks to use
    # The name and mount point association is relevant for parity, do not change it
    # WARNING: Adding here your boot C:\ disk is NOT a good idea!
    # SnapRAID is better suited for files that rarely changes!
    # Format: "data DISK_NAME DISK_MOUNT_POINT"

    Drivepool With Snapraid

    in General

    DrivePool doesn't care about the drives in the pool having drive letters, so you'll be fine there. SnapRAID on the other hand needs to be able to access the drives - if you don't want drive letters for each, then you can mount each drive in an empty folder instead (as long as the drive is NTFS).

    I use the following folder structure: 

    
C:\Snapraid
    \Data
        \1
        \2
        \3
        \4
    \Parity
        \1
    \Cache
        \1
        \2

    Each of the numbered folders is a mount point for a disk - SnapRAID is then configured to point at each of the data drives and the parity drive. Best practice is to set the "root" of each data disk in the SnapRAID config to the hidden Drivepool poolpart directory (because if/when you swap out a disk, Drivepool will assign a new ID to the poolpart directory, so the "root" would change). Also make sure that Drivepool isn't going to do any balancing between the data drives, as that will just cause an excessive number of changes each time SnapRAID runs.

    Since SnapRAID doesn't like it when you write to the disk whilst it's doing a sync/scrub, I also use two cache drives with the SSD Optimizer plugin. These are not protected by SnapRAID, but are instead set up as another Drivepool with duplication enabled, which is then part of the main pool, like so: 

    
SnapRAID (Pool) - Mounted as E:\
 - C:\Snapraid\Data\1
 - C:\Snapraid\Data\2
 - C:\Snapraid\Data\3
 - C:\Snapraid\Data\4
 - Data Cache (Pool)
    - C:\Snapraid\Cache\1
    - C:\Snapraid\Cache\2

    This means that new files are always written to the cache drives, and will not interfere with SnapRAID if it happens to be running, but those files still have protection against disk failure. The SSD Optimizer is the only balancer enabled on the main pool (well, except for the Scanner drive evacuation balancer), and balances into the main pool once a day, so the cache disks only need to be big enough to hold the largest file that is likely to be written to the pool.

    Thank you for the amazing and thorough write up, it is thoroughly appreciated, I think I understand all of this, it seems pretty straight forward. Any chance you could post your snapraid.conf file, I would like to see what one looks like with a setup like this? I am also guessing I should have all by balancers unchecked except the SSD and the StableBit Scanner? With them all turned off Drivepool with just equally fill up each drive as files are copied to it by default, correct, which is the behaviour I want, I do not want any duplication across my main pool, as I will have snapraid, and I have backblaze and a local nas  backup as well.

    As far as my settings page, should I have "Do not balance automatically checked" for the behavior I am looking for?

     

    Again, thank you!!

    Drivepool With Snapraid

    in General

    Posted

    So I am very familiar with using mergerfs and snapraid, just moved my media center from an OMV with unionfs and snapraid setup back to windows. I have drivepool setup with 4 x 4tb hard drives working perfectly. I will be adding a 5tb parity drive and setting up snapraid any day now, just waiting for my drive to get here. In the meantime I do have a backblaze backup and an local backup. My question is, I do not want to have each drive in the pool have to have a drive letter, so can anyone tell me if there is a different way to do this in windows? The plugin for OMV , kinda took care of the parity, content and the configuration file, if its possible to not have each drive have to have a drive letter, does anyone have a snapraid config they could share, and maybe any tips/best practices?

     

    Thanks in advance, any help is very appreciated.
