I know this configuration, but I hope it can automatically bypass the
failed OST,
because I can't make sure when the OST will be failed, mybe my question is
how
to avoid blocking rpc on OST, but instead of return IO error, whenever the
OST is
failed.
2007/3/21, Andreas Dilger <[EMAIL PROTECTED]>:
On the clients run:
lctl dl # list lustre device configuration
lctl --device {failed OST device number} deactivate
Same on the MDS, though the device will be different compared to clients.
This will deactivate the failed OST on the clients so they get an IO error
when accessing any files on the OST, instead of waiting for it to recover.
Cheers, Andreas
