Hello everyone, Anybody had the chance to test out this setup and reproduce the problem? I assumed it would be something that's used often these days and a solution would benefit a lot of users. If can be of any assistance please contact me. -- Met vriendelijke groet, Richard Landsman http://rimote.nl T: +31 (0)50 - 763 04 07 (ma-vr 9:00 tot 18:00) 24/7 bij storingen: +31 (0)6 - 4388

I'm trying to match a ConstantFPSDNode == 0 in dag pattern for tablegen but am having some issues.

Hello all, i have already had a discussion on the software raid mailinglist and i want to switch to this one :) I am having a really strange problem with my md0 device running centos7. after a new start of my server the md0 was gone. now after trying to find the problem i detected the following: Booting any installed kernel gives me NO md0 device.

Hi, I am trying to backup data from a distributed replicated volume.

Hello list, I recently enabled shared storage on a working cluster with nfs-ganesha and am just storing my ganesha.conf file there so that all 4 nodes can access it(baby steps).? It was all working great for a couple of weeks until I was alerted that /run/gluster/shared_storage was full, see below.? There was no warning; it went from fine to critical overnight.

I created a 1TB RAID1. So far it is just for testing, no important data on there. After a reboot, I tried to mount it again # mount /dev/mapper/vg00-btrfsvol0_0 /mnt/btrfs0 mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg00-btrfsvol0_0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or

Hi, There was some problem with our system so I re-installed the server with CentOS 7. Now, when I am trying to run 'fdisk -l' command, it is returning a broken output. It throws this error- "fdisk: cannot open /dev/sdc: Input/output error". There are valid /dev/sdd and /dev/sde devices which are mounted and they are accessible but, somehow /dev/sdc is having a problem and

OK, so our old MDS had hardware issues so I configured a new MGS / MDS on a VM (this is a backup lustre filesystem and I wanted to separate the MGS / MDS from OSS of the previous), and then did this: For example: mount -t ldiskfs /dev/old /mnt/ost_old mount -t ldiskfs /dev/new /mnt/ost_new rsync -aSv /mnt/ost_old/ /mnt/ost_new # note trailing slash on ost_old/ If you are unable to connect both

Hi all, This is the third fresh install of CentOS 7 1708 the last two months that won't boot after a regular "yum update" just after the fresh install has finished. I've never had this problem before, it has just worked. The installs are on OEM's that have previously run CentOS 6.9 x64. Am I missing something here? -- BW, Sorin

Hi, When I perform a software RAID 1 or RAID 5 installation on a LAN server with several hard disks, I wonder if GRUB already gets installed on each individual MBR, or if I have to do that manually. On CentOS 5.x and 6.x, this had to be done like this: # grub grub> device (hd0) /dev/sda grub> device (hd1) /dev/sdb grub> root (hd0,0) grub> setup (hd0) grub> root (hd1,0) grub>

Hey guys, I need to use iostat to diagnose a disk latency problem we think we may be having.

Hello, Arne. I try to build storage server for my home (I have a LOT of media files) with FreeBSD 7, 5xHDD (WD 500Gb) and geom_raid5 ("simple" version from perforce, beacuse http://home.tiscali.de/cmdr_faako/geom_raid5.tbz is not patched for FreeBSD7).
