New Config

Preserve current assignements. What should I choose? none?

If i choose none, i should know to put which drive in which slot right? at least cache drive on cache slot. data drive can be on any data slot. parity drive should be on parity slot.

 

is my assumption correct?

All.

 

It will let you change any assignments before starting. You just need to change the disk12 assignment. Then it will rebuild parity (if you don't check the box) based on the new assignments.

something is wrong.

i change some of the data drive slots and now i think the drive is out of array.

 

 

should i

1. new config

2. preserve current assignmet

 check - parity

 check - cache

 uncheck - data

 

What should I do?

Those are either disk shares, they can appear if set to auto and those disks don't have any user shares (Settings -> Global Share Settings) , if it's not that it means top level folders called disk8 and disk10 exist on some disk(s).

it doesnt look like that before. disk 8 and disk 10 should be in the array.

 

what should i do?

They are in the array.

i took a snapshot of current settings

 

should i set new config like this?

 

after set the new config, i put the drive in the slot as the first image. would that fix the out of array problem?

the contents of those 2 disk are not in the array

Current settings look fine, but refresh the GUI to see if all disks are mounting.

this is what it looks like in the array vs the disk

 

as you can see, the contents of a folder in the array is empty, \\TOWER\Cloud\ijm\move\2019\Movie

but there is contents in the same folder in the disk 8, \\TOWER\disk8\Cloud\ijm\move\2019\Movie

Eons ago i change the settings in the global share settings. i have add those drive to the included disks.

 

unfortunately, the folder still empty.

 

what gives?

this is what my configuration looks like before.

 

 

this is what it looks like now

 

certain folder are missing now.

 

another thing, i put the drive i recovered from ddrescue to the array(straight after ddrescue. no preclear and stuff). would this might be the cause?

Like mentioned, it's related to the disk/share settings, make sure user shares includes all disks and none are excluded.

 

this is my global shared settings

 

all disks are included

 

excluded disks are none

 

i have remove the ddrescue recoverd disk from the array(new config), by the way.

ok. after mounting the drive, i can see the missing folder.

 

i guess i cant mount drive recovered from ddrescue. i need to copy the content recovered by ddrescue to array.

Not sure what you mean but as long as it's working...

 

On share setting included disks should be set to "all"

Post a screenshot of Shares - User Shares from the Unraid webUI. Possibly you have accidentally created some user shares with disk names.

 

I don't recommend even working with individual disks on the network. Best if you don't share any disks and just work with user shares. It can cause confusion and even data loss if you try to work with disks and user shares both.

 

 

here are my user settings.

 

by the way, what happens if during rebuilding parity drive, a data drive failed? since the parity drive is incomplete, i would lost the data in the failed drive right?

Yes, at least partially.

-Tools -> New Config -> Retain current configuration: All -> Apply

-assign a new disk12, start the array, use for example UD to mount old disk and copy to new disk (array) before or after syncing parity

 

Any LSI with a SAS2008/2308/3008 chipset in IT mode, e.g., 9201-8i, 9211-8i, 9207-8i, 9300-8i, 9400-8i, etc and clones, like the Dell H200/H310 and IBM M1015, these latter ones need to be crossflashed.

Do you think an LSI Logic MegaRAID SAS 8308ELP card will work with the current kernel in unraid? It's an older type SAS card with PCIe x4 (not x8) pins. Which is also exactly what I need, since that x4 port is what is still free in my mainboard. Unclear to me what chipset is used in this card (the chip-info is obscured with a marker).

It might, but not recommended since it's a raid controller, not an HBA, also it won't work with >2TB drives.

I can set it to RAID-0 in LSI BIOS.

I used to have an older HP raid P222 controller card that I simply set to use RAID-0 for each drive, which worked for other linux software, so I'm hoping this will work.

It might work, but sill not recommended, one of the reasons is that it might require rebuilding all disks if you change the controller in the future, like this post.

Ah, that's actually a real valid reason I would not immediately think of. I'll do some switching around here between that older LSI Logic MegaRAID SAS 8308ELP and a LSI SAS 9207-8i HBA (I now have in my main desktop with Covecube's StableBit DrivePool). The only issue is that this last card is PCIe x8, this means I have to put it in the x8 slot on this Asrock E3C246D4U serverboard, on which it is shared with the PCI-E x16 slot through a "PCI-E switch" straight to/from the Xeon. The x16 slot now has a card with 3 M.2 NVME SSD's, and the manual says the x16 slot will auto-switch to x8 when that (other) x8 slot is occupied. Not sure if the ssd card is using the full x16 bandwidth. Will have to check..
