Hi all,  new to unraid and i just purchased the Basic version. I put a computer together with some old hardware i had, installed and have Unraid 6.1.18 up and running.

 

Computer Specs:

Mobo: Gigabyte GA-A55M-DS2

CPU: AMD A8-3850

Memory 4096GB 1333mhz

Has a 1000Mb/s full duplex Nic onboard

 

My current hardrive setup is

1tb WD Green (Parity)

1tb Seagate barracuda (Data)

1tb Seagate Desktop (Data)

 

120GB kingston SSD (Cache)

 

I created a share, wondering on the best setting for it.

I left everything on default, set Use Cache disk as Yes

 

Transferring a 21GB file windows estimates about 10-15 mins at speeds ranging between 26MB/s and 30MB/s but peaking at 40MB/s

i have a unmanaged dlink gigabyte switch with both machines connected on

 

So is this the rates i should be expecting, how could i improve it?

What do you guys use your unriad for? i wanted to use it as a NAS and host Plex, Teamspeak and possibly a VM running linux to run as FOG server.

 

Any help would be appreciated. i do like  the unraid software and think it very powerful

take care.

Sounds like speeds you would get writing to a parity-protected disk, not to cache. Are you writing to a cached user share?

I attached the Shares page in the picture.

 

I forgot that was prolly from a external usb3.0 drive

 

So im trying another transfer of my SSD  but its going slow, 10-15MB/s

 

I feel like im missing something,

 

Checking Resource monitor, im not even breaking 1/4 of 1Gbps on the network graph.

And that sounds like 100mb ethernet speed.

 

Go to Tools - Diagnostics and post the complete diagnostics zip.

Here you go,

 

and thank you for your help.

Your syslog is full of this:

Feb 26 22:08:55 unraid shfs/user: cache disk full

Is that true?

Looks like something is wrong here? why is it showing up as no size?

 

is this because of a old partition scheme on it or something? i was thinking unriad would format it like it did with the data drives.

Err, yeah. The FS of the Cache Drive is showing as vfat? I am not sure how you have accomplished that. The only Cache drive FS's supported are RFS, BTRFS and XFS AFAIK.

 

I can't remember what happens when you add a disk to the Cache slot with an exisiting FS BUT as I am working from memory is there a notification on the GUI (Main Tab) asking you to format?

No im not seeing any thing notifying me of something like that. So my next step is to format this drive then, best way to do that?

 

 

Also i'm using XFS on my drives  it seems, what are the perks to each type of filesystem? how can i know which one suits me the best

 

Edit:

 

I found out how to format it, the cache drive filesystem was set to auto, i changed it to XFS and now its giving me a format option, will test once its formatted

 

Edit #2:

 

Transfering a 40GB folder with multiple files in it, im running 80MB/s to 100MB/s and peaking at 90% network utilization. Transfer is suppose to take under 8 minutes. So im feeling better about this now. i didn't realize my cache drive was just doing nothing.

RFS is an older FS and it is all but "recommended" that you use XFS for your data drives now over RFS. As for BTRFS I see no UseCase for using that FS on your data drives. I don't feel it is ready for mainstream use for such a purpose and it certainly seems to suffer FS Corruption much more (based on reports) than other FS's supported by unRAID.

 

That being said, for your Cache drive there is a UseCase for using BTRFS and that is the ability to run multiple disks as your cache in a RAID-1 configuration thus giving you redundancy. It's really your call whether you do that or not considering the instability issues which still seem to plague BTRFS at the moment. I run BTRFS on my Cache Pool of devices as I know do many others. I know no-one in the community who is running BTRFS on their data disks.

 

Back to your Cache Drive Setup. As I have no idea how you got to where you are I feel the need to start from scratch.

 

1. Ensure you have no important data on your Cache devices. I am assuming you don't given the last Screenshot but thats your call to check.

2. Stop the array

3. Remove the drive from the Cache slot in the GUI.

3. Reboot.

4. Click on "Disk" at the top (if your are using Tab's).

5. Look at the very bottom of the page in the Disk Devices section for a disk 'slot' labeled Cache (the very last slot).

6. Select any disk not in the array into that slot.

7. Go into the disk properties by clicking "Cache" and select the FS you want the disk to be formatted to.

8. Start the array.

9. Watch for any prompts to format the disk on the Main Tab after you start the Array.

 

Then lets see what happens ....

My Cache drive Filesystem was set to Auto, i switch it XFS and it formatted after. so thats all good now.

Good Stuff. Nice speed too. Happy Days.

Also, remember to add the label [sOLVED] to the thread title of the first post.
