Greetings, First of all, I want to preface by saying I have had very bad luck with extending linux filesystems. My situation is this: I had a 4TB Hardware RAID5 (3x2TB) in a Fedora Box. I use this array for backups, files, music, lots of things. Recently it started to grow low on space, so I procured a 4th 2TB drive, and added it to the Hardware RAID. No issues with that. The RAID BIOS shows the new ~6TB Capacity. What I am having trouble doing is making Linux extend it's partition to the ~6TB size. The RAID is device SDC1. SDC1 is a member of the volume group vg_3ware. I'd appreciate some help. All of the tutorials and howtos I've found seem useful, but I always get stuck because i only see the original ~4TB size in Linux, and not the new size. Thanks! C
Falko, Thanks for the post, I appreciate the time. I did consult the LVM guide. It's pretty comprehensive. However, my partition table is using GPT because 6TB is too large for DOS. Using the guide as a refernce, I was able to make the partition 6TB using parted. Code: [root@buster ~]# parted /dev/sdc GNU Parted 2.3 Using /dev/sdc Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) p Model: AMCC 9590SE-8ML DISK (scsi) Disk /dev/sdc: 6000GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 17.4kB 6000GB 6000GB primary This is great, however using e2fsck gives an error that the device is in use: Code: [root@buster ~]# sudo e2fsck -f /dev/sdc1 e2fsck 1.41.12 (17-May-2010) e2fsck: Device or resource busy while trying to open /dev/sdc1 Filesystem mounted or opened exclusively by another program? I'm not sure if there is a trick to figuring out what is using the device, especially since it's not mounted. Any advice is much appreciated. Thanks! C
