there are 2 suspicious disks on db1 and 1 on storage1.
The smart test was never executed on storage1. I will launch one on both servers to have fresh data

vsellier updated the task description. (Show Details)

the test is still running on one disk on storage1 (sdb). No new errors were discovered on all the other disk

The test of /dev/sdb finally ends ... in error :

SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error
# 1  Extended offline    Completed: read failure       80%     26004         2559298584

So we have 2 disks to replace on each server. What's weird is that the 2 disks to replace are at the same position on each server...

The model number to use on the request is : ST6000NM0115
There is an obscure message limiting the number of return / country / year to 3 (!):

The priority is storage1 as there is one offline disk and only one remaining spare. So its 2 disks will be replaced.
For db1, /dev/sdb (ZAD27C4P) will be replaced as it's a spare and it will be simpler to replace.

well well well

It seems nothing is done to have an easy warranty between the site that works when it has time and the replacement conditions :

It seems we will have to schedule the replacements progressively.

Precision around these disks replacement, even if the disks are in error, there is still spares on the zfs pool:

+ another disk removed from the pool which we will replace first in T3033

storage disks will be replaced in T3243

closing this issue as the quota of disks replacement will be over after T3243.
The disk on db1 looks stable for the moment. It will be removed from the zfs pool in case of problems.
