On my desktop, I try to instantly put some disks into sleep using hdparm, for some tests. Though the disks are unmounted, they wake back up in seconds. How can it be? How can I track which process wakes a disk up with what operation? I think unmount disks should default to standby during system load.
View 2 RepliesI have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)
Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?
I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?
I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);
dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)
(a new server,2 CPU 8 core and 8 gb ram)
1000000+0 records in
1000000+0 records out
1024000000 bytes (1.0 GB) copied, 12.9662 s, 79.0 MB/s (I have not used this server yet) (hw raid1)

I have lots of HDD on my PC and I just mount them to access files, I am wondering if these drives are turned off when unmounted? because I want to remove them physically on my computer unplug its IDE and power cable while ubuntu is running, wont it damage the drive even if its unmounted?
View 5 Replies View RelatedI just upgraded from Karmic to Lucid and have the following problems:
(1) My unmounted partitions used to be visible in "Places" on the left of Nautilus, so I could mount them when needed, but now they are not there. Also,they do not show in "Computer" view
(2) When I open Disk Utility from System/Administration, there is nothing at all showing - it takes quite a while to start up, but when finally the window opens, no devices or partitions are shown.
I have two internal disks that are accessible from my ubuntu. I installed ubuntu using wubi, and those two disks are the same disks I use on Windows. One of the disks contains windows system files.These disks were easily accessible from ubuntu, I could mount/unmount anytime I wanted and had no problem with editing files. I did something I can't remember, I was just following some instruction trying to solve problem with my SD card reader. turned out it wasn't the right solution (but I fixed the SD card issue using some other instruction).
View 4 Replies View RelatedTypically when I'm given a SAN attached to one of my servers i'm not given any information on it. Usually I can get my with an fdisk -l to tell me what's out there. Twice now I've had to ask what the connection device is. What command can be run other than fdisk -l, I've seen something ran people by another guy but was not able to write it down at the time and have forgotten it.

Is there a way to check what caused Ubuntu to wake from suspend mode?
Ubuntu 10.10 on a desktop.
Have tried disabling all BIOS wake events (and WOL).
Have ensured mouse doesn't move.
Need a way to know what caused it to wake. Happens 90% of the time, usually 3 seconds after it suspends.
I have an Intel DG35EC motherboard with on-board NIC. It is an Intel 82566 Gigabit NIC. It is wired, not wireless. I am using an Ubuntu "Live CD". Just out of curiosity (to see if it worked), I "suspended" Ubuntu and it suspended very well, but when I "resumed" Ubuntu the NIC would not connect back to the network. If I actually installed Ubuntu and didn't use a "Live CD" do you think it would behave differently?
View 1 Replies View RelatedUpgraded to Ubuntu 10.10 recently. (Now that was a mistake...) Problem occurring now that when I close lid of my laptop (Asus K40IN series) , which I set to suspend, it won't wake up (and I have to shut down and reboot). It used to be fine (in both Windows and 10.04) though so must've something to do with the upgrade to 10.10.
View 2 Replies View RelatedI dual boot both Windows and Linux and I often put my computer to "sleep" at night so it's easy to wake up the next morning. In Windows I just need to press a few keys and my computer comes to life, in Linux this doesn't happen and I have to actually go for the power button. (This wouldn't be so bad if the computer wasn't in a hard to reach place in a cupboard) At the moment I have a USB hub which my keyboard and mouse plug into, but for the sake of testing I plugged a second USB keyboard directly into the machine itself, again neither wake it. Doing a bit of research I have discovered that the wakeup devices are stored in /proc/acpi/wakeup The contents of the file by "cat" are as follows:
Code:
monotoko@KatieIV:~$ cat /proc/acpi/wakeup
DeviceS-state Status Sysfs node
PCE2 S4*disabled pci:0000:00:02.0
[code]...
At this point I have reached a dead end, how do I tell the acpi wakeup to accept input from USB keyboard as a kickstart?
When I remove "safely" my usb pendrive all my hard drives and partitions get unmounted. It's not permanent I just have to close the session and start again but sometimes it's kinda annoying because I'm in the middle of a lot of work and have to close everything... and if I'm working with a file in that drive sometimes I lose it...
View 1 Replies View RelatedI have a Debian OS installed (6.0), installed on a single partition, which was running out of space. So I copied all the data in /home to a spare partition, then edited fstab to mount this new partition as /home.
This works fine. But now of course I have the /home data both on the new partition (the one that is now being mounted and used), and also still on the original partition, though this directory is no longer mounted by the OS, so I can't directly 'get at' the data to delete it.
I could easily get into the partition from another OS and delete the unneeded /home data of course but I was just wondering; as this data is no longer 'seen' by the OS, will it be overwritten automatically by the OS when it needs more space, as it does with data that has been deleted from the filesystem, or would it be reserved somehow, still using up space?
I have two volumes, both with 800GB total used on them. lets call them /vol1 and /vol2. /vol2 is just a cron'd rsync'd copy of a folder on /vol1 which is a live share for many users.If I temporarily suspend the cronjob doing the rsync's from /vol1 to /vol2, is it safe to unmount and e2fsck /vol2, then remount it somehow?
Both /vol1 and /vol2 say the filesystem state is not clean when i do a tune2fs -l on them both. According to tune2fs both will check themselves upon restart, but if I can do /vol2 since it isn't the live data beforehand, that will cut my downtime in half the next time i restart the server.But I also wonder that if I can do this, then i remount /vol2, will the "not clean"-ness of /vol1 just be rsync'd back over to /vol2 the next time the rsync runs?
I accidentally unmounted filesystems using umount -a command.How to recover from this.
View 4 Replies View RelatedI've got Karmic installed on an HP 6930p, and with relatively little intervention, all hardware has been supported beautifully. I'm using the ATI driver for graphics. Battery life increased dramatically after an update a couple of months ago. However, occasionally (1 in 8 times maybe), the screen is black when waking from suspend. Disk wakes, etc, but the screen is off. Trying to re-suspend with fn key doesn't work. Ctrl-alt-f key combos don't work. I have to hold the pwr button down.
View 5 Replies View RelatedSince installing 10.04 yesterday my laptop will not wake correctly from sleep mode. Opening the lid wakes the machine up but the graphics are all wrong. Loads of tightly packed horizontal lines. Turning the machine off and restarting makes all ok. It's only on wake up does the problem happen. The laptop is an Acer 1652,with an ATI Mobile Radeon X300 graphics card. Intel Pentium M.

For some reason, all of the sudden;
-my computer quit waking from suspend
-when my computer reboots (because I had to hold in power switch until it restarted) some of the items on my screen looks wierd for a few minutes, like there are tracers on some items (dock, top of screen, etc)
-when i try to wake my computer from suspend, the screen is a funny gray color with wierd blobby shapes that move around a little bit. And of course, doesn't load GUI or anything like that, just gray screen.
I am running Ubuntu 10.10 on a Lenovo T60 and am having problems waking up from sleep every time I update the kernel.
I just got the upgrade from 2.6.35.25 to 2.6.35.27.
The problem I see now is that I get this message when coming back from sleep (I coped it down since after the message I couldn't do anything else):
pciehp 0000:00:1c.0 pcie04: Device 0000:02:00 already exists, cannot hot-add
pciehp 0000:00:1c.0 pcie04: Cannot add device at 0000:02:00
I checked my pci listing and the device on 0000:02:00 is my ethernet adapter:
shahars@shahars-ThinkPad-T60:~$ lspci | grep 02:00
02:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller
ever since i upgraded to 11.04 + gnome 3 the computer freezes to the point that the mouse doesnt move... for 30 seconds or so Also,if i put the computer to stand by, many times doesnt wake up properly, looks like the graphics are corrupted the mouse moves jamming until it fully freezes

I have a dual boot laptop Ubuntu 10.10 + Windows XP. When browsing my Windows C Drive in Ubuntu I decided to create a share to the windows "my documents" folder. The problem is that the windows drive is not automatically mounted at launch of ubuntu and as a result I get the following errors:
Code:
Could not find "/media/14F0AD48F0AD30C2/Documents and Settings/Lucas Redding"
and a search box is launched (See Attached Image).
I have tried to look at the Samba and Nautilus settings but I am unable to find any that automatically mount the windows drive.
Under KDE (3.5) in Lenny, whenever I "safely remove" a SD card, I get the following message
"The device was successfully unmounted, but could not be ejected"
The message is obviously ridiculous, and the crashing windows error sound that accompanies it very annoying.
How can I see all the physical hard drives on my Ubuntu system — regardless of whether they're mounted — as well as their partition info, sizes, &c.? I have three physical drives, but only one seems to be mounted. I'd like to mount the other ones too, as I have some data on them.
