[PVE-User] OfflineUncorrectableSector, and now?!

[Marco Gaiarin]

On a DELL PowerEdge T440 we got:

 Subject: [alerts.veneto] SMART error (OfflineUncorrectableSector) detected on host: pspve2

 This message was generated by the smartd daemon running on:

    host name:  pspve2
    DNS domain: ps.lnf.it

 The following warning/error was logged by the smartd daemon:

 Device: /dev/sda [SAT], 8 Offline uncorrectable sectors

 Device info:
 HFS480G32FEH-BA10A, S/N:ESABN5131I080BA2O, WWN:5-ace42e-025406ebe, FW:DD02, 480 GB

 For details see host's SYSLOG.

 You can also use the smartctl utility for further investigation.
 The original message about this issue was sent at Wed Nov 16 15:00:46 2022 CET
 Another message will be sent in 24 hours if the problem persists.

Disk is an SSD one, connected to the server controller PERC H750 Adapter put
in 'NonRAID' mode (some sort of JBOD).


RAID controller firmware (via iDRAC) says that the disk are full
operational.

I've tried to do some smartctrl shor test, but nothing hapened (so, no error
found i suppose).


Can i safely ignore this? There's some way to say to smartctl that '8 Offline
uncorrectable sectors' are good, and go over?


Thanks.

Yes, this is something you can verify in IDRAC, storage, physical disks, 
wear leveling.

Exactly; the strange thing is that: if i look at iDRAC:

Well, it seems HFS480G32FEH-BA10A is a Hynix SE5031. I did not find its
specs but for different models, Hynix specs say that ID 198 is:
Offline Scan Uncorrectable Sector Count / The number of uncorrected
errors

It is maybe a bit worrisome but the normalized value of its attributes
is still at 100. This SSD does not seem to be (currently) dying. Do you
have ZFS on top of it? Have a look at its SMART attributes in a couple
of months.
I see that it is a Dell SSD. Do you have any contract support? You
could ask to their support what they think of it.

DELL support say that disk is good.


Thre's some way to disable daily SMART email, eg defining that '8 bad sector
is good'? Clearly without disabling SMART at all...


If i've understood well, 'smartd' send notification using scripts in
'/etc/smartmontools/run.d/', and particulary:

	/etc/smartmontools/run.d/10mail

I've to code a custom script?


I've used to have smartd signal disk trouble once, and reading manpages
seems that this is still the default behaviour...

Re: [PVE-User] OfflineUncorrectableSector, and now?!

[Stefan Hanreich]

These warnings get governed by the configuration in /etc/smartd.conf

The only line in the default configuration line looks like this:

DEVICESCAN -d removable -n standby -m root -M exec 
/usr/share/smartmontools/smartd-runner

You can change this to the following line to only get email 
notifications when the value of SMART attribute 198 increases:

|DEVICESCAN -U 198+ -d removable -n standby -m root -M exec 
/usr/share/smartmontools/smartd-runner |

You can find the documentation for this file in the respective man page [1].

Kind Regards
Stefan

Seems like there were some issues with the formatting of my last mail, 
so I am writing again:

The default config looks like this:

DEVICESCAN -d removable -n standby -m root -M exec 
/usr/share/smartmontools/smartd-runner

This would need to be adapted like this:

DEVICESCAN -U 198+ -d removable -n standby -m root -M exec 
/usr/share/smartmontools/smartd-runner

Kind Regards
