On my RHEL system, I gave the following command:
# file -sL /dev/sd*
Here is the output that I received:
/dev/sda: x86 boot sector; GRand Unified Bootloader, stage1 version 0x3, boot drive 0x80, 1st sector stage2 0x849fc, GRUB version 0.94; partition 1: ID=0x83, active, starthead 32, startsector 2048, 1024000 sectors; partition 2: ID=0x8e, starthead 221, startsector 1026048, 103831552 sectors, code offset 0x48 /dev/sda1: Linux rev 1.0 ext4 filesystem data (needs journal recovery) (extents) (huge files) /dev/sda2: LVM2 (Linux Logical Volume Manager) , UUID: ZwRo1k6K3XhyqeAUkqQuvMPCoW7leEF /dev/sdb: data
Request your help in understanding what the above means.
- Pls validate if this means that I have 2 partitions on my HDD namely, sda and sdb
- sda is further divided into sda1 & sda2. sda1 is ext4 format type and sda2 is LVM2
- sdb is of file system type data.
- What is meant by 'data' type (in #3) above?
