Re: [CentOS] Filesystem labeling confusion or mess up
What are partitions on your disk? We use label for a partition with certain filesystem. Also check /proc/partitions Thanks Vishesh kumar Linuxmantra.com Sent from my iPad On 28-Nov-2013, at 4:55 am, Cliff Pratt enkiduonthe...@gmail.com wrote: *Something* is causing it to appear that there are two paths.

Hi Cliff, theer is just one path; I rechecked. The storage and server are attached currently direct with one twinaxial cable and just one ip on each side. Multipathing was never configured.

Hi, I do have an iscsi storage with two raidsets. I'm logged in to the target and get two devices: /dev/sdb and /dev/sdc.
