Hi All,

Its a 2 node RAC setup with ASM

When i run partprobe on both nodes I found below output:

NODE 1:

device-mapper: remove ioctl on mpathap2 failed: Device or resource busy

device-mapper: remove ioctl on mpathap1 failed: Device or resource busy

Warning: parted was unable to re-read the partition table on /dev/mapper/mpatha (Device or resource busy). This means Linux won't know anything about the modifications you made.

device-mapper: create ioctl on mpathap1 failed: Device or resource busy

device-mapper: remove ioctl on mpathap1 failed: Device or resource busy

device-mapper: create ioctl on mpathap2 failed: Device or resource busy

device-mapper: remove ioctl* on mpathap2 failed: Device or resource busy

NODE 2:

Warning: parted was unable to re-read the partition table on /dev/sha (Device or resource busy). This means Linux won't know anything about the modifications you made.

When I list all the disk partitions from location /dev/mapper and /dev/dm-* i found below output:

NODE 1:

ll /dev/mapper/

I found that mpatha, mpatha1, mpatha2 are not in node 2. Why this is like this. Is this is Fine or I am not on the right track.

I am confused, that weather I am on the right path or not. Please guide me so that i can move further, i got stuck.

Thanks

Akash
