In one of interview of RHEL I have been asked following question. Please help me in getting answers
1) Without using dmesg command and messages and dmesg log file, how one will find that hot pluggable drive just inserted has been detected by kernel or not. 2) Are device file corresponding to this drive will be created automatically? If no which command will create corresponding block device file in /dev. 3) If these is no way for automatic generation of block device, how major and minor number of a disk can be figured out so that one can use mknod device_name b maj_no Minor_no? 4) If this disk is configured and partitioned successfully. One has copied /boo, / , /var and /usr of running system to this disk on corresponding directory. What has to be done to write bookable super block /MBR on this disk so that one can boot from this disk on next reboot. 5) without using dmesg and message file, how one can get prior information that a particular disk is malfunctioning and going to crash / fail.
