how to replace parity drive without loosing protection?
Michael_P replied to MoherPower's topic in General Support
Just do one at a time if uptime is your primary goal, "protection" would be just limited to 1 disk failure -
when I install apps it showed SSL verification failure

Are you running a pihole or pfblockerng on your network for DNS? -
Cache Pool is breaking randomly - ReadOnly Filesystem

If the system is sending corrupted data, the age of the SSDs is irrelevant -

If bad memory is corrupting your data, changing file systems won't stop the corruption - it'll just stop telling you about it. -
Help me recover Please....(2 Drive Failure)
Michael_P replied to abuzzbuzz's topic in General Support
I have that same case, looks pretty much the same too 😆 I've had it for over 20 years now, most recently it was pulling duty as a windows media center pc living in a closet, retired it 2 weeks ago As for your drives, should be able to mount them in any *nix distro if they're still alive -
Bitrot: Can bits on a hard disk unintentionally change?
Michael_P replied to Jaybau's topic in General Support
That's not rot, that's an error. URE's would still be logged (in theory) as an error by the drive and can be immediately recognized if monitored by the OS. The theory is that it will pretty much guarantee the death of a normal RAID implementation since drives are well above 12~ TBs now, and read failures during a, for example, RAID 5 array will drop a disk during rebuild and thus the array will be lost. It's only theory tho, as the MTBURE is not set in stone. It's a guess as to the chance, and even then the drive is likely to recover from the error anyway. IMHO, bit rot and URE are WAAAAAAY less important to worry about than just keeping backups of your important data, and verifying your backups -

Yes. But unlikely (random cosmic ray blasts a bit on the drive for instance), the drive would still likely report a read error. Data "decaying" in any reasonable amount of time, really unlikely. -
Bitrot an issue? Or is there already a fix in unraid?

*if the drive reports the error -
It'll look like this, then you can match the serial# to the disk #:

Anything behind your VPN does not require any other paid services to access, you simply connect via a client to your VPN to access anything behind it. Anything you want to access OUTSIDE of your network can be done thru a paid VPN, but the two are mutually exclusive.
-
What are you trying to use the VPN providers for? If your services are behind your VPN, you just need to access the VPN with your client.

Keep splitters to a minimum if at all possible, and no more than 4 drives per molex connector or you will start to exceed it's current handling capability and the drives will start behaving badly (it's also a fire hazard)
