Hello,

Mon NAS est hyper lent depuis quelques jours.
Des transferts de quelques kb/s confirmé par un iperf.
Je n'ai pas encore corrélé mon problème de débit avec cette erreur en terme
de timing :
Jun  1 00:18:42 freenas ahcich3: Timeout on slot 16 port 0
Jun  1 00:18:42 freenas ahcich3: is 00000000 cs 00030000 ss 00000000 rs

Jun  1 00:18:42 freenas (ada3:ahcich3:0:0:0): Retrying command

Est-ce que les lenteurs ont commencé avec çà .... ?
Ca veut dire qu'un disque est en train de mourir non ?

Côté réseau, ma carte dit çà :
bge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0
mtu 1500

options=c0099<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,VLAN_HWTSO,LINKSTATE>

Or ça, c'est un rsync --progress de backup en cours ....

32 heures pour un fichier de même pas 2 Go. Bon je suis pas pressé mais ....

Mon tests smart dit çà :

Le temps d'un iostat "pour voir" => reboot : panic ?

2 questions :
- est-ce grave ?
- est-ce que ça peut dégrader à ce point les débit réseaux ?
