nice i think you will be happy with it

Advice please.   🧐

I am running three x 8-bay Synology NAS arrays, all populated with matched sets of Seagate 10TB IronWolf HDDs.

One HDD has failed (just out of warranty after 3 years), and I am having trouble finding an exact replacement.

I would prefer a new Seagate IronWolf ST10000VN0004 10TB - which has been discontinued. I can't find one with a Google search, local and overseas.

I have a spare ST10000VN000 10TB and a spare ST10000VN0008 10TB.

Would a ST10000VN000 be a suitable substitute in an ST10000VN0004 array?

(This is the first HDD failure that I have experienced in the last 20 years.  Lucky me. 🙄)

@Sideface why do you think you need matched drives? i currently have 5x8TB Western Digital enterprise drives, 1x 8TH WD Red and 2x WD Red Pros. and it runs flawlessly. i have a couple of spare drives, 1x 8TB and 1x 12TB drive should i need them. I would just make sure they are all the same speed as this may impact the arrays performance.

i assume you are running SHR (Synology Hybrid Raid)? if so any drive greater than 10TB will work fine. A 10TB drive will give you the best use of space, and any drive bigger than that, the NAS will only use 10TB of. So if you are adding bigger drives in an SHR then its best to add them in two's.

What do you keep on your 3x NAS's?

Just curious, what type of files are you storing with that much data? Movies? Like I struggle to use 4TB atm as mostly I stream stuff or store in-cloud?

 

Jase2985:  ... What do you keep on your 3x NAS's?

 

I have about 40TB of high-res music files on each of 3 RAID arrays - triple redundancy in 3 locations.

All other files are on another set of 3 smaller RAID arrays, again with triple redundancy in 3 locations.

Nothing in The Cloud.

The Cloud is somebody else's network on somebody else's computers in somebody else's country.

This is an ultra-cautious habit from my old CIO days, before I retired.

Ironically, it was not required until now.

The damaged array is RAID 5.

Perhaps move on from raid 5 so that matched drives is no longer a thing you need to worry about?

Should be fine as i mentioned above. A 10TB drive of the same RPM would be your best bet, With raid-5 any larger drive will just start wasting the extra space.

no way to change without starting from scratch, but given they have 2 entire spares should be achievable, all be it a long process

UPDATE: 

Acting on the advice of the NZ Synology / Seagate distributor, I have successfully repaired the broken RAID 5 array with a new IronWolf ST10000VN0008 10TB HDD.

Same brand, same size (10TB), same sector size (512), same speed (7,200rpm) as the existing array.

(I'll keep looking for an original N0004, but I don't fancy my chances.)

Thank you all for your advice.  🙂

What are people doing to backup their NAS?

I have a mate with the same NAS as me (1219+) and i would like to backup a couple of folders to his NAS. I dont want to back up the entire shared folded, but some folders within that shared folder. My friend also has to be able to access the data that's being shared, so any form of backup/replication is out.

I have, and am currently trying Synology Drive Sharesync, but it doesn't allow scheduling or speed limiting which is a little annoying especially is there is a large bit of data added, which i would prefer goes overnight, and the controls and info that is provided in the package is limited.

I liked the look of shared folder sync via rsync but it appears you can only sync the root shared folder, not individual nested folders. but it appears to have a lot more controls and information in it, especially scheduling and speed limits.

ive also looked into a docker container with syncthing but while it has a GUI webpage it appears to have a bit of CLI involved which im keen to stay clear of as it a bit of a learning curve, and it seems to be pretty fussy with folder permissions. 

anyone else use anything or can suggest something that would suit?

I'm running rclone on my Synology boxes. I run it multiple times in a simple script to backup selected directories to OneDrive and Google Drive. Due to file name length limits (file names are encrypted, adding to the length), I have to exclude one directory from the OneDrive backup and backup that one on Google Drive instead. It's fairly easy to control which are included/excluded. You can create your own targets, using SFTP and other protocols, so backing up to another NAS should be relatively straightforward.

When I eventually get my new NAS setup (long story), I may move the backup off the NAS and onto another box, but I will stick with rclone.
