Hi, Is it safe to run tune2fs -c -1 -i 0 /dev/sda2 on mounted file system Basically, this is a command to disable fsck based on reboot count & last fsck time. -- Regards, Sherin

I want to replace an existing 32bit with a 64bit installation (Centos 5). There's an existing LVM with lots of partitions. Most are used for Xen guests. The system itself uses only one of them plus a separate /boot partition that is not on LVM. What's the best course of action here? Should I do the reinstall with kickstart or better manually and reuse the existing filesystem? As I

When I change /etc/fstab from /dev/mapper/lvol001 to /dev/lvm_pool/lvol001, kernel 3.10.0-514 will boot. Kernel 3.10.0-862 hangs and will not boot.

I did the following test: ############################################### 1. Computer with Centos 7.5 installed on hard drive /dev/sda. Added two hard drives to the computer: /dev/sdb and /dev/sdc. Created a new logical volume in RAID-1 using RedHat System Storage Manager: ssm create --fstype xfs -r 1 /dev/sdb /dev/sdc /mnt/data Everything works. /dev/lvm_pool/lvol001 is mounted to

Hi, The actual data will be in the hot tier only till demotion. The file that you see on the cold tier is just a linkto file of the file on the hot tier. These linkto file are necessary for the internal working of the tier.

Hi Guys Got a quick question regarding hot tier and cold tier. I got a gluster volume with 1 x 3 hot tier and 1 x 3 cold tier. watermark-low is 75 and watermark-hi is 90. usage of volume is very less. My files always go to hot tier and cold tier at same time As I understand, data should go to hot tier only until demoted. Could someone please shed some light into this? Thanks in advance. --
