I believe I've posted before about one of the speed issues we were having, of backups taking many, many hours that should *not* take that long. My manager and I finally nailed it down to the h/d itself. Identical boxes, and he tried a backup of one system which took under two hours, while the same regular one rand nearly six. I'd been googling on and off for weeks, and this morning, ran

Can someone please explain what's wrong here. And how to solve it. I run CentOS-4.1 MSI K8N Neo Platinum Athlon 3000 Seagate Barracuda 7200.7 S-ATA disc [root at amd64 kai]# /sbin/hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2808 MB in 2.00 seconds = 1402.81 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads:

At the present moment, my guest is running inside qemu and host is kvm intel, running Ubuntu 14.04, kernel is 4.3.0 stable. From within the guest, when I run "hdparm -i /dev/sdb" on the guest, I get: HDIO_GET_IDENTITY failed: Invalid argument as the error,but on the host, I will get the full harddisk/SSD info. Can I know how to resolve this so that the output is the same for both

Hi, I was wanting to run the equivalent of "hdparm -Tt /dev/hda" except on a SATA hard disk. What is the equivalent command for an SATA drive? I was wanting to see what kind of speed I am getting on the SATA drive. thanks, Jerry

I'd like to to put the hard drives in standby mode during periods of no activity. I'm just running a file server plus a couple small things on a Qube 3 from home, although the web stuff will increase it's still minimal. On my NetBSD systems I can use atactl to do this via: mount -u -o async,noatime,nodevmtime / mount -u -o async,noatime /usr atactl wd0 setidle 5 [wait a time]

Hi, I run a little router/firewall that also acts as a print server for the linux and win98 clients on the LAN. I have the harddisk configured so that if there is little activity, it spins down (hdparm -S 12 /dev/hda). I added smbd/nmbd today and with the two services running, the hard disk drive spins down but wakes up about every 12 minutes. Without the services, only a major event causes them

After booting into Linux 2.6.18-8.1.3.el5xen #> hdparm -tT /dev/sda /dev/sda: Timing cached reads: 10512 MB in 1.98 seconds = 5306.82 MB/sec Timing buffered disk reads: 210 MB in 3.02 seconds = 69.58 MB/sec Then I start a domu with the command: #>xm create <domainname> This domain uses file based Virtual block devices. And now the hard drive performance goes down

Hi there: As suggested in the docs, I am forwarding a bug report. I have just converted two partitions to ext3 from ext2 without reformatting on my home box. All is not well, however. Here's the specs AMD K6/2-3D 500 Mhz, 64MB SDRAM, 100 Mhz bus Via Apollo P5MPV3 chipset, 100 Mhz bus Opti Mad 16 931 soundcard Video= AGP S3 Trio, w/8MB RAM, PS/2 mouse. Realtek 8029 pci bus network card.

I've got a brand new .5U P4 system running several (I think) Seagate 80gig SATA drives. I tried to copy data from the first drive (sda) to the second drive (sdc) and was only getting about 1.7megs/sec. So I figured DMA was off. And this is what happened when I typed "hdparm -d1 /dev/hdc": /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted

OK, I have managed to get software RAID 1 running on my wonderful Proliant server but now have two challenges: 1) Fresh after an OS install and reboot, the RAID array starts to do its stuff but straight away (as part of the boot messages) I am told that the second disk is 'not ready for command' and the system hangs as soon as resyncing starts. I think this is fixed by adding an hdparm

What F/OSS does "secure erase"? And does it do

Hello Everyone, Since rebooting my Centos 6.10 Openvz server "daisy" yesterday, I am getting horrible system performance.? /var/log/messages is full of HDIO_GET_IDENTITY failed for /dev/sdb.?

I upgraded my Centos 4.7 server last night. Switched from a cheaper 50$ asus motherboard to a Supermicro motherboard. I also, using dd, copied entire 500g SATA seagate drive to new 500g SATA seagate drive so as to have two copies in case something went wrong. Anyway, now I keep getting this error: Nov 21 06:08:33 server kernel: hda: status timeout: status=0xd0 { Busy } Nov 21 06:08:33 server

hi :) when using ext3, i can't get my hard disks to go to standby mode any more. i am using timeouts set by hdparm with 2.4.18 kernels. even when i issue a standby command manually, the disk spins up again after a few seconds. however, (to my knowledge) no user space program accessed this disk at that time. i suspect ext3's journal to be causing the disk accesses. is that possible?

Though quiet at the moment, my desktop sometimes sometimes makes a noise that I attribute to either a disk or a fan on its last legs. I'm looking for suggestions for distinguishing. For the disk, I expect I should use either hdparm of fsck. Even after reading the man page, I'm not sure how I would use hdparm. If I use fsck, what should I take as evidence of a bad drive? A good drive? Is
