Migration Raid1 Vers Raid5: Plus D'acc

[mightor]

Bonjour,

J'ai ajouté un 3e disque dans mon DS412+ et j'ai lancé la migration de mon volume1, de RAID1 (disques 1+2) vers RAID5 (disques 1+2+3).

J'ai suivi cette procédure: http://forum.synology.com/wiki/index.php/How_to_expand_the_RAID_Volume_with_additional_disks

Au début tout semblait bien se passer et puis au bout d'un moment, je n'ai plus réussi à accéder au gestionnaire de stockage. Depuis, je n'arrive plus à accéder à l'interface Web du NAS. Et mes ordinateurs n'accèdent plus aux dossiers partagés par le NAS.

La seule chose que j'arrive encore à faire, c'est me connecter en SSH. Et lorsque j'essaye de lister le contenu du dossier /volume1, la commande "ls" ne répond pas. Je peux en revanche lister le contenu du volume2 (disque 4, BASIC) avec la commande ls sans problème.

Le NAS est sur onduleur, il n'y a pas eu de coupure. Et pour le moment, je ne l'ai pas forcé à rebooter.

Je sais que ce genre d'opération peut durer longtemps (plusieurs jours), mais tout les témoignages indiquent que pendant ce temps, le NAS reste accessible, ce qui n'est pas mon cas.

Qui peut m'aider ?

Merci d'avoir lu jusqu'au bout !

En ssh que donne cette commande :

cat /proc/mdstat

[mightor]

La commande n'affiche aucune réponse et ne me rend pas la main, même après plusieurs minutes. J'ai du l'interrompre avec Ctlr+C.

[gaetan.cambier]

alors, c vraiment pas normal, la commande devrait affiche de manière instantannée l'etat du raid :s

et un "uptime" donne quoi ?

[mightor]

DiskStation> uptime

14:24:43 up 20:37, load average: 394.75, 392.76, 386.37

[gaetan.cambier]

v te donner le mien, tu va comprendre :

DiskStation> uptime
 14:23:35 up 11 days,  5:05, load average: 3.62, 3.56, 3.49

bon, serieusement, il y a quoi qui prend autant de ressource sur ce nas ?

la commande "top" permettrait de le savoir, si elle veux bien fonctionner vu que le nas est completement surchargé

[mightor]

Voilà

Sinon, la connexion au nas par SSH est rapide et les commandes répondent rapidement (uptime, top). sauf celles qui coincent bien sur (cat /proc/mdstat et ls /volume1).

[gaetan.cambier]

alors ement je comprend pas :

le cpu n'est pas surchargé (99% idle)

il y a de la ram libre --> pas de risque de swap

reste plus que un disque deconne a fond et fasse tout ralentir pour avoir un load average si haut (et après les 2 commande, il a augmenté)

on va essayé de verifier les disque en ligne de commande :

smartctl -a -d sat -T permissive /dev/sda

idem pour sdb ...

[mightor]

/dev/sda:

DiskStation> smartctl -a -d sat -T permissive /dev/sda

Les disques semblant saints, la question que me taraude maintenant, c'est: que faire ? Attendre ? Est-ce que le NAS est encore en train de faire quelque chose de constructif avec ce volume ? Faut-il le redémarrer ? Va-t-il continuer l'opération de migration du raid dans ce cas ?

Et la plus importante: y a-t-il une chance de récupérer ce volume et son contenu (partages, contenus) ?

[gaetan.cambier]

redemarrer, c'est pas trop conseiller qd on modifie le raid

question bete, tu est passé de 2 à 4 disque en 1 seul fois ?

pour moi, juste le laisse faire, et essayer de laisser une fois tourner la commande "cat /proc/mdstat" pour avoir la reponse du raid

[mightor]

Ok je laisse encore tourner.

Je suis passé de 2 (RAID 1) à 3 disques (RAID 5). Le 4e disque est dans un 2e volume, sans redondance.

Je laisse tourner la commande cat /proc/mdstat toute la nuit, verrai le résultat demain.

[mightor]

Voilà donc le résultat: pas de réponse. La commande "cat /proc/mdstat" ne répond pas du tout.

Le problème dure depuis plus de 36 heures maintenant.

Et toujours pas de réponse à la commande cat /proc/mdstat

Comment savoir si le processus de construction du RAID5 est en cours sans cette commande ? Combien de temps au maximum cette conversion de RAID1 vers RAID5 (3To pleins à 99%) peut-elle prendre ?

[gaetan.cambier]

moi j'avais mis + de 36heure pour ajouter un 5° disque à mon raid6 (seulement 2to à resynshro par disque)

[mightor]

Le taux d'occupation des IO te semble-t-il indiquer que le NAS procède effectivement à la reconstruction du RAID ?

[gaetan.cambier]

suis pas devin, mais il utilise apparemment beaucoup les disques, ca doit pas etre pour riren enfin j'espère

[mightor]

"Patience et longueur de temps..." comme disait un Français célèbre. Vais retourner bosser, ça m'occupera l'esprit pendant que le NAS se dépatouille.

[mightor]

Bon, sur recommandation du support, j'ai fait un hard reset et retrouvé l'usage de mon NAS, avec toutes mes données. Analyse des logs en cours au support pour déterminer la cause de ce fiasco.
