[Two ssds drives disappears and are now 'Not installed"]

Hello

I recently has two problems with two ssds, I lost the first one few days ago, but I had a time to copy my files to another disque, after that I deleted the ssd of my array and make a new config without this one.

After that, another ssd crashed, I wasn't able to go inside the folders, instead of that I had: NO LISTING: TOO MANY FILES. 

So I tried to repair the disk using the method: Checking and fixing drives in the webGui.
I tried but unfortunately without success, I wasn't able to run: -nv or any others commands, nothing happen after click on "check"

So I switch from maintenance mode to normal and from this action the disk 9 is now mentioned like: "Not installed" ...

I m a bit lost 😅  I m of course afraid to lost all the data from the disk 9...

Please kindly find attached my diag files...

 

Thanks for your time

[After format SDD disk 3.8tb with UD I ve got formated disk at 1tb !]

1 hour ago, trurl said:

I think you are using the word "pool" differently than is meant with Unraid. Disks in the parity array are referred to as array disks.

 

The usual place for SSDs is in pools outside the parity array. Cache is a pool named "cache". You can have multiple pools of multiple disks, and name them as you wish.

https://wiki.unraid.net/Manual/Storage_Management#Pool_.28cache.29_Operations

 

 

Yep yep you totally right

thanks for the tips 😅

 

When I said pool I meant the ssds in the array ...

 

I read many many post about Unraid and SSD, I understood that there is no trim with the array.

 

But I don t really understand the real risk. 

 

I have array with 2 HDD as parity disk.

 

and 6 ssds + 2 HDD + 2 HDD for parity .

 

I use Unraid only for Plex, so I don t write a lot fo date on the SDDs, only when I had movies, so mainly to ''read'' datas.

 

So the risk is the SSDs crashes and lost the data ? And the parity won't work to rescue the data, is it right ?

 

 

 

Thanks a lot ! 

[After format SDD disk 3.8tb with UD I ve got formated disk at 1tb !]

Hello, 

 

thank you for your answer ! 

I finally get them back and run well ...

I use to pass by preclear for all my disque before to setup for the pool

 

My parity drive are seagate ironwolf 8tb x 2 

 

So you mean it s kind of useless to use SSDs in my serveur ?

I only have SSD as a pool and HDD as parity, isn't a good way to make it work fast? 

 

"Do you know that SSDs in the parity array cannot be trimmed and can only be written at parity speed?"

Actually I didn't know ... 😅

You mean PARITY SSD can't be trimmed but the SSD in the pool can ? 

 

I use Unraid only for PLEX, so I don t write a lot on the SDD only to copy movies, the ssd disk montly use for read data ... 

 

What do you suggest  ? Better to use regular HDD, in the pool and for the parity?

 

 

Thanks a lot for your help !

[Replacing HDD BY SDD Size problem ...]

Thanks ChatNoir !

If I understood well:

 

- I stop the Array, I add the to array the new SSD 

Now I have all the hard drive + new SSD

 

( In MAIN, I can't replace the HDD by the SSD because is smaller and Unraid don t allow me to do it ) It say ''WRONG" ( like on my picture above )

So I ll copy the file with unBALANCE then remove the HDD  

 

 

Thanks you !

 

 

[Replacing HDD BY SDD Size problem ...]

Hello ! 

I have Unraid server with 10 HDD 8 TB 

I bought few SSD 8TB to replace theme but .... 

When I follow the replacing process, when I have to select my SSD to replace sur HDD Unraid told me that it s impossible because the size must be bigger than the previous HDD ...

Is there any solution ? The HDD are not full at all

Hello,

I already have a custom server running well, but I need more power ... 
I have a DL380P G8 that I can transform to unread server; I tried but isn't working  ... I guess is because I have a pic 420i  ?

I can see only one of my HD  with name LOGICIAL

 

I read can I can buy a card like HPE H220. is it a good solution ? Is it plug and play ?

I found this on Ebay: HP h220 6gbs PCI-E 3.0 Adaptateur HBA LSI 9205-8i 9207 p20 IT
 

Thanks a lot for you advise

Likely gone, the result of the filesystem corruption.

 

Yep.

 

No, it would rebuild the same contents as now, parity can't help with filesystem corruption, also you should always have backups of anything important.

 

 

Thanks again for your help ! 

 

ok so I have to copy past the files, open each folder so it s like impossible because of the number of files ... 

 

I even lost the name of the file 😅 so weird ...

 

 

[[SOLVED] 2 disks failed after electrical shutdown …]

Thanks !

 

yes there are many files and movies in the folder lost and found. 

Before the hard drive crash the disk 5 has 210 GB left, Today 4.20TB, I don t get where is the reste of the files ?

 

 

what can I do ? Do I need to copy them in the right folder manually ? One by one 😅? 

 

 

Maybe is a stupid question, but if I remove disk 5, I format it, them I can re build it using the two parity hard drive and get back my missing files?
 

 

[[SOLVED] 2 disks failed after electrical shutdown …]

Thanks again for your help ! 

 

I did everything you advise, I also change the cable. Now everything is looking ok but I lost many movies on my library Plex ( around 450 movies lost) 

I don t understand why ... 

I thing I lost files from disk 5 it was quiet full, and now is almost empty after the re building

 

How it s possible?

[[SOLVED] 2 disks failed after electrical shutdown …]

What is not working? Disk are now mounting, they weren't before, they are still disable, that is expected, you need to rebuild them to fix that, but first they have to mount and show the correct data.

Thanks

so I just need to Check will start Read-Check of all array disks ?
