Scheduled Maintenance Report for Bare Metal Cloud
Completed
Concernant les serveurs SSD: nous avons trouvé une incompatibilité
entre le software smartctl AND certains disques SSD 32nm AND \"parfois\".
En gros, le soft smartctl permet de regarder l'état du disque et les
éventuels erreurs. Parfois, la smartctl n'arrive pas à récupérer cet
état du disque et la requête arrive en timeout, ce qui provoque un reset
hard SATA2 du disque. C'est un bug mineur qui n'empêche pas le bon
fonctionnement du serveur. Néanmoins, on conseil de ne pas utiliser
smartctl en attendant que les ingénieurs Intel fixent ce bug mineur.


Update(s):

Mise à jour du Intel case 9399705:
\"The issue has been reproduced and confirmed again that it is caused by the solid state drives not supporting Read Log Ext ATA.

The command smartctl -a /dev/sda displays all SMART information from the drive, including the SMART self-test log which is what is calling
the Read Log Ext ATA and it fails then.

So, it is possible to use other smartctl commands and get all the other SMART information without causing the failure.

For example, the following commands will work fine:
smartctl --attributes /dev/sda - displays all SMART attributes
smartctl --health /dev/sda - displays overall SMART health status of the drive

It appears that a fix is planned in a future firmware version of the solid state drives but I cannot tell exactly when we can expect that
firmware release.\"

Mise à jour du Intel case 9399705:
\"We received response from the escalation regarding the SMART error when using the Intel?? Solid-State-Drive.
The issue has been investigated and it appears to be related to the fact that the drive does not support READ LOG EXTcommands.
The only workaround at this point is not to use READ LOG EXT. The performance of the drives should not be affected by this.\"

Nous attendons d'avoir une date de correction du problème de la part d'Intel.

Intel case 9399705 - Intel X25-M Solid State Drive

confirmation de la part d'Intel du bug

I have replicated the issue with Debian 5 using a laptop not a desktop board
and I escalated your issue to the US-engineers. Currently I am awaiting
feedback.

Nous avons desactivé les logiciels smartd et smartctl sur les nouvelles installations et
les réinstallations pour toutes les machines qui comportent des ssd.
