In an Oracle VM Server we created a 2nd partition on /dev/sdb, now we want to create the ext4 filesystem on it, but mkfs -t ext4 /dev/sdb2 returns this:
mke2fs 1.43-WIP (20-Jun-2013)
/dev/sdb2 is apparently in use by the system; will not make a filesystem here!
Here's the result of parted:
[root@OVSGRIENSU ~]# parted /dev/sdb
GNU Parted 2.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print
Model: IBM ServeRAID M5210e (scsi)
Disk /dev/sdb: 999GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 53.7GB 53.7GB ext4
2 53.7GB 999GB 945GB datos1
As you can see, this disk is handled by the RAID controller IBM ServerRAID M5210e. This is a one disk array, the only way to let the O.S. see each disk was this.
How can we create a filesystem for /dev/sdb2?.
