Hello All, So My Drobo finished formatting and I added an entry to fstab for it and now I cannot boot the machine. I get an error about fsck.ext3: is a directory while trying to open /drobo and then a mention of a valid super block I had mounted the Drobo as /drobo and in 'fstab' I copied the line for '/' changing to ext3 where it was ext4. I have made a mistake I cannot fix

Hi all, I used a kickstart script to setup a new machine of mine with RAID 1 (I couldn't get anaconda to create matching partition schemes). So I've now got /dev/sdg1 and /dev/sdh1 as 'bios_grub' (/dev/sd{a-f} are a separate array). 0 root at an-nas02:~# parted /dev/sdg print free Model: ATA ST3000NC000 (scsi) Disk /dev/sdg: 3001GB Sector size (logical/physical):

Hello all, I have run into a sticky problem with a failed device in an md array, and I asked about it on the linux raid mailing list, but since the problem may not be md-specific, I am hoping to find some insight here. (If you are on the MD list, and are seeing this twice, I humbly apologize.) The summary is that during a reshape of a raid6 on an up to date CentOS 6.3 box, one disk failed, and

> I'm having an issue getting a C6.6 install to work on a 3 TB dual hard >drive system, raid 0. I'm hoping that someone here can help. 1: Is this system booting UEFI or BIOS? 2: Is the disk partitioned with MBR or GPT? 3: Is /boot on its own partition? 3TB drives are larger than MBR and BIOS properly support, so they're only really expected to work on a system partitioned with

I have run into a problem attempting to attach the seventh virtio-scsi device to a RHEL 6.4 Guest from a RHEL 6.4 host running libvirt version 0.10.2-18. I have a guest that is running RHEL6.4 where I can attach disks sda(boot), sdb, sdc, sdd, sde and sdf but when I try to attach sdg the virsh attach-disk command fails with the error: error: Failed to attach disk error: internal error Unable to

HI All, I have a dilemma and I would appreciate advice 1. Get a good size case, mobo, processor, etc and put 8 hard drives it in and RAID them. (yes an 8 port SATA mobo). Running CentOS. or 2. Get an eSATA enclosure that has room for 8 or 10 drives and just connect it to box? I know that RAID is not a full proof backup, but I am looking for a solution to store all of my data, projects, music,

I?ve posted this on the forums at https://www.centos.org/forums/viewtopic.php?f=47&t=57926&p=244614#p244614 - posting to the list in the hopes of getting more eyeballs on it. We have a cluster of 23 HP DL380p Gen8 hosts running Kafka.

All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one. Here is an iostat example from a host within the same cluster, but without the RAID check running: [root at r2k1 ~] # iostat -xdmc 1 10 Linux 3.10.0-327.13.1.el7.x86_64 (r2k1) 05/27/16 _x86_64_ (32 CPU)

Hi Folks, When I boot ISOLinux, the locally attached disk is visible but the PATA 40 Gig in a USB attached enclosure is not. The locally attached disk has no bearing on what I am doing and to avoid confusion will not be mentioned again. Everything is happening on the 40 Gig. Let me explain. The goal is: Copy an installation iso to the disk, boot the disk and install it on that disk. I have

Hello everyone. I am having trouble with rsync stopping in the middle of a transfer. Everything works fine for smaller batches of file, but when I try to rsync big groups, it just stops in the middle. I have been using rsync to copy my home directory to an SD card. I recently got a Drobo+Droboshare (NAS) and want to do the same thing to the Drobo, but when I run rsync, it stops somewhere in

Ok, I give up... I have to ask. This is CentOS 5. I switched one of my raid1 disks, and I already thought I had succeeded. But now it seems that something is very wrong with the first partition on the new disk. Luckily my system is fully bootable with the other disk. Here's some info. The new disk is sdb. // I removed all partitions with parted, and created the first one again. // parted
