Merci pour vos réponses.

J'ai pu reconstruire le raid. (et comprendre ce qu'il se passait)
Il me restera donc à demander le remplacement.

PS: Tuto très bien fait!

[Nowwhat]

Même si montre des signes de fatigue, je te conseille de le remettre à sa place http://denisrosenkranz.com/tuto-mdad...raid-logiciel/ - chapitre "Simuler une panne de disque".
Faire des sauvegardes est toujours un bon idiée.

Si OVH est d'accord pour changer le disque sdb, à priori, t'as pas besoin des tes sauvegardes.


Le 'tuto' te montre aussi comment il faut faire pour préparer la sortie d'un dsqiue (sdb), puis comment activer un nouveau disque. http://denisrosenkranz.com/tuto-mdad...ue-defectueux/

[bendevos]

ha oui merci c'est déjà moins ennuyant si il n'y a pas besoin de restaurer le backup...


bon je vais revérifier les backups et faire faire le remplacement à ovh.
merci pour vos lumières

[derinhger]

donc si j'essaie de résumer la situation.
j'ai un seul disque HW qui était configuré en raid software (sda et sdb sont des mirroirs)

Tu as deux disques physique SDA et SDB configurer en RAID1

il y a eu des erreurs et sdb est sorti du raid (probablement suite à une partition pleine et un redémarrage)

Je dirait plutôt due au fait que SDB présente des erreurs

il faut faire changer le disque HW par ovh (parce que ?)

Car il présente des erreurs 184 Reallocated_Sector

je perdrai toutes les infos suite à cet échange et donc il faudra tout recopier depuis un backup externe.

Non, normalement pas de soucis de perte de données, ton SDA étant en bon état, mais le BACKUP peut te sauver la vie, si par un coup de mal chance ce dernier venais a claquer avant/pendant la resynchro du RAID

c'est bien çà ? pas moyen de refaire le raid soft sans changer le disque ?

Si tu peut toujours essayer de resynchro le RAID, mais autant remplacer avant le disque déffaillant, car dans un premier temps, pas sur que la synchro fonctionne correctement, et deuxiemement tu devra de toute façon le refaire quand tu voudra changer le SDB, car ce dernier n'est pas en grande forme

SDB:
1 Raw_Read_Error_Rate 0x000f 118 099 006 Pre-fail Always - 197191688
5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 184

Pas en pleine forme le petit, dans un premier temps tu devrais déjà t'assurer d'avoir des BACKUPS a jour et externe a la machine
Ensuite remplacer le disque et resynchro le RAID

[fritz2cat]

Il faudrait savoir pourquoi ton sdb est sorti du RAID.
Pour l'instant tu ne tournes que sur une patte et tu prends des risques.

[bendevos]

est -ce que cela vous aide ? (je reçois toujours ces messages... merci

[bendevos]

moi aussi je me suis fait avoir ;-)
ca donne ceci

aaargh ! je me suis fait avoir avec tes deux smartctl du même disque !!!

et smartctl -a /dev/sdb, ça donne quoi ?

Tes disques n'ont pas l'air défectueux, mais tes deux disques md1 et md2 ne sont plus sécurisés en miroir raid1.

Il faudrait donner plus d'info sur ta configuration (tables de partition, etc) car il y a quand même un truc bizarre, sda1 d'un côté et sda2 de l'autre qui se retrouvent isolés.

[bendevos]

Personne n'a d'avis sur cette question ? Je continue de recevoir des messages d'alerte.


Merci d'avance!

[bendevos]

Bonjour,

le script de monitoring raid soft me donne cette erreur depuis deux jours:
par contre avec smartctl , je ne vois rien de "cassé"

une partition du disque a été pleine un instant, est ce que cela peut etre la cause du probleme ? Y a t il une opération à effectuer pour "réparer" le RAIDSOFT ?

merci d'avance

A DegradedArray event had been detected on md device /dev/md2.

Faithfully yours, etc.

P.S. The /proc/mdstat file currently contains the following:

Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] [faulty]
