[gpfsug-discuss] Disk in unrecovered state

[Grunenberg, Renar]

Hallo Iban,
first you should check the path to the disk. (mmlsnsd -m) It seems to be broken from the OS view. This should fixed first. If you see no dev entry you have a HW problem. If this is fixed then you can start each disk individuell to see there are something start here. On wich scale version do you are?

Betreff: [gpfsug-discuss] Disk in unrecovered state

Dear,
   Since this moning I have a couple of disk (7) in down state, I have tried to start them again but after that they change to unrecovered.
   These "failed" disk are only DATA. Both pool Data and Metadata has two failures groups, and set replica to 2. The Metadata disks are in two different enclosures one for each filure group. The filesystem has been unmounted , but when i have tried to run the mmfsck told me the I should remove the down disk

   [root at gpfs06 ~]# mmlsdisk gpfs2 -L | grep -v up
disk         driver   sector     failure holds    holds                                    storage
