[SOLVED] disk wearout question

[RobFantini]

is there a way to use smartctl or another cli tool to verify the wearout number at pve > system > disks 'wearout' value ?

[ we have 30 Intel s3610 , and all of them show 0% wearout. ].

That's strange, s3610 are supported by smarmontools. (used by proxmox).

Do you have a passthrough controller ? or a raid controller ?

you can try to update database of disk model with:

/usr/sbin/update-smart-drivedb

Hello - thank you for the reply,

we have IT mode LSI cards .

I'll work on updating the database..

Here is more info. I assume 233 = wearout , the 233 value seems very high:

true and as you may already know the developers kept it out for a good reason: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=804299

Here is more info. I assume 233 = wearout , the 233 value seems very high:

233 Media_Wearout_Indicator 0x0032 100 100 000 Old_age Always - 2184793

what is important here is not the 'raw' value, but the normalized one, and this is stlll at 100
from [1]:

Reports the number of cycles the NAND media has undergone. The normalized value declines linearly from 100 to 1 as the average erase cycle count increases from 0 to the maximum rated cycles. Once the normalized value reaches 1, the number will not decrease, although it is likely that significant additional wear can be put on the device.

thanks for the reply.

I had read that 'normalized' is the number to look for, however in pve > disks and smartctl -a the word normal does not appear so there is a little guess work to be done.

the good news is that all 30 used disks [ bought at less then $100 each ] are as good as new. with our write rate will last 50 years.

the gui has a column which is named 'normalized'

I see now. got to double click on a row to get to that. Thank you.
