Hello I have a CentOS 6.6 Server with 13 disks in a RAID 6. Some weeks ago, i upgraded it to 17 disks, two of them configured as spare. The reshape worked like normal in the beginning. But at 69% it stopped. md2 : active raid6 sdj1[0] sdg1[18](S) sdh1[2] sdi1[5] sdm1[15] sds1[12] sdr1[14] sdk1[9] sdo1[6] sdn1[13] sdl1[8] sdd1[20] sdf1[19] sdq1[16] sdb1[10] sde1[17](S) sdc1[21] 19533803520 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [15/15] [UUUUUUUUUUUUUUU] [=============>.......] re...

Hi all, I'm setting up Centos4.2 on 2x80GB SATA drives. The partition scheme is like this: /boot = 300MB / = 9.2GB /home = 70GB swap = 500MB The RAID is RAID 1. md0 = 300MB = /boot md1 = 9.2GB = LVM md2 = 70GB = LVM md3 = 500MB = LVM Now, the confusing part is: 1. When creating VolGroup00, should I include all PV (md1, md2, md3)? Then create the LV. 2. When setting up RAID 1, should I make those separated partitions for /, /home, and swap? Or, should I just make one big RAID device? The future...

CentOS 5, original kernel (xen and normal) and everything, Linux RAID 1. I rebooted one of my machines after doing some changes to RAID/LVM and now the two RAID partitions that I made changes to are "gone". I cannot boot into the system. On bootup it tells me that the devices md2 and md3 are busy or mounted and drops me to the repair shell. When I run fs check manually it just tells me the same. mdadm --misc --detail tells me that md2 and md3 are active and fine. I wanted to comment out the md2 and md3 devices in fstab (and hoped then be able to boot) but I get a "...

Hi list, I'm new to Centos and I've a very small knowledge of selinux use. I can disable it, but I prefer take it on for study. I've a second mirrored device that I use for file sharing. This is the scenario: /dev/md2 mounted on /mnt/data To make samba working I must set the file context to the path at samba_share_t on /mnt/data. After this samba works. Now I'm setting up postgresql on the same machine, and for first disk size I must use /dev/md2. After configuring postgresql script to init the db, and...
