35000 power-on hours. SMART still reports it as OK.
Time to figure out how to rebuild a RAID 5 array. The other two drives are probably nearly cooked too, but I have plenty of spares that I got for free.
Perfect occasion for one of the remaining drives to die during resilvering. I hope your backups are up to date?
“Yeah, I just saved them to the NAS earlier today before it started making noise”
- User about to have a bad day, possibly me in the future…
My predecessor at work had a “backup scheme” where each week a full copy of important VMs’ virtual disks would be pulled by a backup VM. Two issues with that. One, the VMs were not powered off and nothing ensured that the disks were synced. Two, the backups were made onto the same physical host with no replication or high availability beyond RAID 1.
Yeah, at the moment I am building a home server running TrueNAS, it is the only backup I will have, but it is far better than having everything on a single HDD in my computer…
I need the final two HDDs to set up my raid and start using the server.
I have a question about my raid though.
Is it better to run it with four data drives, one parity, and one hot spare, or should I run it with four data drives and two parity drives, and no hot spare?
I am running 8TB Seagate Iron Wolf Pro drives, from (hopefully) separate batches.
The CPU is an AMD Ryzen 4600G and I have 32GB ram in it.
I want to add another SATA controller and add two SSDs, one for L2 cache, and one for applications and VMs, as well as add a low profile GPU for transcoding and later a 10G NIC
No backups. For important documents and photos, that was the backup and most of them have copies on my PC. The rest is easily replaced. I knew what I was getting into, and that the free, decommissioned hard drives with 20-30 thousand hours on them were a lit fuse.
Looking into making my own NAS, where’d you get these?
Benefit of my job: I get access to the scrap pile. I don’t know any reputable used/refurbished sellers.
Maybe look into the 3-2-1 backup scheme while you’re at it.
I know what it is, and I ensure compliance at work (I’m a sysadmin). At home, it’s less about best practices and more about what hardware I can afford. Manufacturers tend not to offer regional discounts. A 2-2-0 scheme is better than nothing at all.
You’re probably already working on replacing it, but SMART returning “okay” doesn’t rule out a failing disk. What you want to look for on SMART tests are the RAW value of reallocated sectors. Anything over 0 is a bad sign.
Also check temperature, if the noisy boy is also hotter then it’s neighbors… That’s a strong indicator
