[ubuntu] pb sur controluer sata & Raid :( Need help !!

Marsh Posté le 15-08-2011 à 13:28:21

Bonjour tous le monde

J'ai besoin de votre aide car j'arrive à bout là
j'ai un serveur Atom - Ion qui me sert d'HTPC avec XBMC dessus
très jolie très fonctionnelle c'est cool

En dessous, j'ai une ubuntu natty (11.04) d'installée sur un disque SSD (32go) et j'ai un Raid 5 avec 4 Disque de 2 To (des samsungs, peut être est là l'erreur :s )

depuis peu (env 1 mois) j'ai un pb avec les accés disques , je ne peux ps regarder de films sur mon HTPC sans que ca rame voir même écouter de la musique

j'ai regardé et ca vient du fait (si je comprend bien) que mon contrôleur SATA ne fait que de redécouvrir les disque (extrait de mon kern.log)

En gros si je comprend bien, mon disque fait le yoyo entre déconnecter et reconnecter .... et du coup ca fait écrouler mes accès disque .... c'est inutilisable
cela se fait aussi sur les autres disques apparemment (ata4, etc..)
Je suis en:

Citation :

2.6.38-10-generic-pae #46-Ubuntu SMP Tue Jun 28 16:54:49 UTC 2011 i686 i686 i386 GNU/Linux

J'ai essayer de rollbacké en kernel plus ancien (2.6.36 ) sans gain .

Je ne sais plus quoi faire je ne sais pas si c'est ces disques qui sont pbmatique (mais pk maintenant ? ca fait 6 mois que l'htpc tourne)

Merci de votre aide et piste , j'ai pas d'idée hormis de changer tous les disques pour des disques moins GREEN , plus pour du RAID (mais je ne crois pas que cela viennent de ça )

ps : j'ai essayé de désactiver la mise en veille des disques mais sans résultat

A priori, ca viendrait d'un pb de cable SATA et/ou power:
http://lime-technology.com/wiki/in [...] ace_Issues

Citation :

These are problems with the cables and connections to the drive, both power and data, or the quality of the power supplied. If your errors match one of these, then almost certainly, your drive is completely fine. There have been many drives returned or thrown out, after numerous errors similar to the following issues, that were entirely the fault of the cables or power or connectors used, NOT the drive itself.
Drive interface issue #1
An example:
ata3.00: exception Emask 0x50 SAct 0x1 SErr 0x280900 action 0x6 frozen
ata3.00: irq_stat 0x08000000, interface fatal error
ata3: SError: { 10B8B BadCRC } often may also include DisPar, UnrecovData, and/or HostInt
From an expert:
"Your machine seems to be suffering genuine link layer problem.
In most cases, this indicates hardware problem and in my experience,
common causes are (in the order of ballpark frequency)...
# inadequate power supply
# device and controller don't like each other on 3Gbps
# cable too long or flaky connector (especially with eSATA cables or genders or backplanes)
# faulty controller or drive"

(written by one of the foremost experts)
The presence of BadCRC is a pretty good indicator of a poor quality SATA cable. However, if a better cable does not solve the issue, then it is probably a power problem (loose power cable or backplane connection, poor connectors, poor power splitter, overloaded power supply, too many drives on power rail, bad power supply, etc).
