On CentOS 5, the current centosplus kernel doesn't want to play with the kmod-gfs package (because kmod-gfs wants the stock kernel): # yum install kmod-gfs gives me: Transaction Check Error: package kernel-2.6.18-8.1.14.el5.centos.plus (which is newer than kernel-2.6.18-8.1.14.el5) is already installed Should it work, or is there a separate centosplus build that I've not

We have a machine that's a distro mirror - a *lot* of data, not just CentOS. We had the data on /dev/sdc. I added another drive, /dev/sdd, and created that as /dev/md4, with --missing, made an ext4 filesystem on it, and rsync'd everything from /dev/sdc. Note that we did this on *raw*, unpartitioned drives (not my idea). I then umounted /dev/sdc, and mounted /dev/md4, and it looked fine; I

Look for a single drive that has substantially greater await than ~10msec. If all the drives except one are taking 6-8msec, but one is very

Hi, I am currently running a 10 Node OCFS2 Cluster (version 1.3.9-0ubuntu1) on Ubuntu Server 8.04 x86_64.

Hi, I have a host which is connected to SAN via single Fibre channel HBA (qlogic). I have several LUNS assigned to this (sdc, sdd). I added another single port HBA to this host. I can now see two world wide names. Now the confusion is which world wide name does sdc and sdd is/was using. scsi_id -g -u -s /block/sdc only gives wwid but I need the wwn for sdc and sdd. Thanks Paras.

Everyone, Is there a way to manually assign usb drives to a specified device label. Is there a way to force two usb drives to be labeled as /dev/sdc and /dev/sdd? I decided to build an archive server for the purpose of backing up other fedora/centos desktops at the office. I built a machine and have installed Centos 7.3 on it with all updates current. I also purchased a 3.0 usb sata drive

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. Basic specs: 2x E5-2650 128 GB RAM 12 x 4 TB 7200 RPM SATA drives connected to an HP H220 HBA Dual port 10 GB NIC The drives are configured as one large

Hallo, linux-btrfs, please delete the option "-L" (for labelling) in "mkfs.btrfs", in some configurations it doesn''t work as expected. My usual way: mkfs.btrfs -d raid0 -m raid1 /dev/sdb /dev/sdc /dev/sdd ... One call for some devices. Wenn I add the option "-L mylabel" then each device gets the same label, and therefore some other programs

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)

I am running zfs-fuse on an Ubuntu 10.04 box. I have a dual mirrored pool: mirror sdd sde mirror sdf sdg Recently the device names shifted on my box and the devices are now sdc sdd sde and sdf. The pool is of course very unhappy about the mirrors are no longer matched up and one device is "missing". What is the proper procedure to deal with this? -brian -- This message posted from

Hi folks! Been using btrfs for quite a while now, worked great until now. Got power-loss on my machine and now i have the "parent transid verify failed on X wanted X found X" problem. So I can''t get it to mount. My btrfs is spread over sda (2tb), sdc(2tb), sdd(1tb). Is this something that an offline fsck could fix ? If so is the fsck-util being developed ? Is there a way to

Dear Devs, I have x4 4TB HDDs formatted with: mkfs.btrfs -L bu-16TB_0 -d raid1 -m raid1 /dev/sd[cdef] /etc/fstab mounts with the options: noatime,noauto,space_cache,inode_cache All on kernel 3.8.13. Upon using rsync to copy some heavily hardlinked backups from ReiserFS, I''ve seen: The following "block rsv returned -28" is repeated 7 times until there is a call trace

Hi, folks, testing zfs. I'd created a zpoolz2, ran a large backup onto it. Then I pulled one drive (11-drive, one hot spare pool), and it resilvered with the hot spare. zpool status -x shows me state: DEGRADED status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to continue functioning in a degraded state.

I'm using Centos 4.5 right now, and I had a RAID 5 array stop because two drives became unavailable. After adjusting the cables on several occasions and shutting down and restarting, I was able to see the drives again. This is when I snatched defeat from the jaws of victory. Please, someone with vast knowledge of how RAID 5 with mdadm works, tell me if I have any chance at all
