Hi, I have a doubt if I use the mke2fs option the right way. I formatted two different disks, one with $ mke2fs -b 4096 -E stride=16 -m 1 -T news /dev/sdd and the other with $ mke2fs -b 4096 -E stride=16 -m 1 -T largefile4 /dev/sde sdd is supposed to get files between 8k and 16k. sde will handle files with a fixed size of 32Mb. Then I tried this : $ dd if=/dev/zero of=/mount-sdx/file bs=4k

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

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

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)

Hello All, I have installed Oracle Cluster Manager on linux x86-64 nit. I am using ocfs file system for quorum file. But I am getting following error. Please see ocfs configureation below. I would appreciate, if someone could help me to understand if I am doing something wrong.

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

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.

Hi All Currently i'm setting up a 5.4 server and try to create a 3rd raid device, when i run: $mdadm --create /dev/md2 -v --raid-devices=15 --chunk=32 --level=raid6 /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg /dev/sdh /dev/sdi /dev/sdj /dev/sdk /dev/sdl /dev/sdm /dev/sdn /dev/sdo /dev/sdp /dev/sdq the device file "md2" is created and the raid is being configured. but somehow

Hello, I'm using HP homeserver where host system run CentOS 6.3 with KVM virtualization with SELinux enabled, guests too run the same OS (but without SELinux, but this does not matter). Host system installed on mirrors based on sda and sdb physical disks. sd{c..f} disks attached to KVM guest (whole disks, not partitions; needed to use zfs (zfsonlinux) benefit features). Problem is that disks

I just noticed that by running by commands /usr/sbin/smbd -D or /usr/sbin/smbd -i without systemd's unit, all shares work perfectly so the problem must then be somehow related to systemd.. Let the testing continue.. I also tested what happens if I comment out everything and just use ExecStart=/usr/sbin/smbd -D as that command worked on the console. That did not help. For the record, this is

Hi All, I don't know enough about when errors are *really* errors. So I google a lot to read and learn.

Hi all, I just installed centos 5.4 xen-kernel on intel core i5 machine as dom0. After some hours of syncing a raid10 array (8 sata disk) I noticed a steadily increasing loadavg. I think without reasonable i/o wait or cpu utilization the loadavg on this system should be very lower. If this loadavg is normal I would be greatful if somone could explain why. The screenshots below show that there is

Hi, I have an iscsistorage which I attached to a new centos 6.3 server. I added logic volumes as usual, the block devices (sdb & sdc) showed up in dmesg; I can mount and access the stored files. Now we did an firmware software update to that storage (while unmounted/detached from the fileserver) and after reboot of the storage and reatache the iscsi nodes I do get new devices. (sdd &

CentOS release 4.5 Hi All: First of all I will admit to being spoiled by my MegaRAID SCSI RAID controllers. When a drive fails on one of them I just replace the drive and carry on with out having to do anything else. I now find myself in the situation where I have a failed drive on a non-MegaRAID controller, specifically an Adaptec 29160 SCSI controller. The system is an Acer G700 with 8
