How to block some disks from probes on Linux boot?
- by Igor Velkov
My linux host connected to SAN with FC interface.
It connect with one path, and see some luns, that can't access, because they need anohter path, not available to host.
On boot linux probe all lun he can see, get read error on unaccessible luns, and hangs there for a long-long time.
Is there a way to disable any access to some luns at boot time, and later?
I found a filters for device ignoration for LVM and MULTIPATH, but it not help during boot process.
Generally, lvm still affected too despite of filter, and gives me a IO error on every operation like lvdisplay and vgdisplay, but this is another question.
