Re: [Moosefs-users] missing/unavailable chunks

[Deon C. <deo...@gm...>]

Hi mooseys,

I have experienced something similar in the last few days over the weekend.
It appears in my case that one of my chunk servers is experiencing a kernel
panic every now and then and crashing.

Upon reboot, ZFS was consistent but moose report missing chunk. Luckily it
has only been a tmp file, so the loss of it causes no harm.
However it is distressing to me that ZFS can "lose" the data, or moose is
reporting to the application writing the data that it is committed to disk
when it isn't.

Boris if moose is reporting a missing chunk then it is likely your chunk
servers have done something with them, like in my case.

Regards,
Deon
