Occasional temporary freezes on disk access (SSD)
I'm using a SanDisk SD5SG225 SSD, and occasionally get random lockups with the disk light stuck on. These pauses last for about 2-4 seconds, and usually occur when I save a file, open a new tab, etc. The program that is using the disk will freeze. I'm using LUKS (no LVM) and had discard with LUKS passthrough enabled, but currently have it disabled.
Here is my fstab:
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
# /dev/mapper/root UUID=8448cc36-99f5-4c90-b310-5688a447089f
/dev/mapper/root / ext4 rw,relatime,data=ordered 0 1
# /dev/sda2 UUID=a26bb41c-3354-4f28-9a50-d02f7629b00b
/dev/disk/by-partlabel/boot /boot ext2 rw,relatime 0 2
/dev/disk/by-partlabel/efi /boot/efi vfat rw,relatime 0 2
I'm not sure what other information to include. Any help would be appreciated: I'm scared I'm ruining the SSD somehow.
Same problem here. Intel SSD.
Examples of things that cause the temporary freeze (where the mouse pointer moves but extremely slowly):
Playing an embedded Youtube clip on a page in Chromium
Trying to add a printer in hp-setup
HALP!

Temporary freezes after fitting SSD and new ram
I recently replaced the internal HD in my MacBook Pro with a 250GB SSD from OWC and doubled the ram to 4GB at the same time. I'm very pleased with the improvement in performance, except that I now get temporary freezes for as long as 20-30 secs. I can move the cursor around and click but nothing happens. When The computer 'comes back' it responds to what I did while it was 'away'. This happens several times a day.
Any ideas what might be going on here?
Thanks in advance,
Steve = : ^ )I have a SSD installed and I don't get any of that. I also don't use Safari, I use Chrome.
The SSD I installed is a Kingston SSDNow V200 128GB. It has been running fine for 2 months.
One big reason I use Chrome is because it allows me to sync all browser data across many different computers.
If I change, add or delete a bookmark it gets updated on all my computers. If I save or delete a login username & password for anything it get updated on all computers.
But I digress.
As to your problem I'd call OWC and tell them your problem. And you could try putting the original drive back in and see if you get any freezes. If you do them it may be the RAM. If you don't then it is the SSD. -
[SOLVED] Long time with excessive disk access before system reboot.
I feel I would be grateful for some help here. It's my first go at Arch Linux having used Xubuntu for several years. It may be I'm missing something obvious but then I would be happy if someone could point me in the right direction.
Problem: When I do a system restart by issuing
$ systemctl reboot
I get the following output

mdadm: stopped /dev/md126
[ 1654.867177] Restarting system.
However, after the last line is printed, the system does not reboot immediately but hangs for about 2 minutes with heavy disk activity. I can't say if it is read or write or both, but the led of my HDD is lit constantly. When this activity stops, the machine reboots.
$ systemctl poweroff
works as expected, i.e. shuts down immediately without excessive disk access.
I see this behaviour both with the installed Arch system and when I run the live installation/recovery CD. It is also the same if I boot into the busybox rescue shell and then restarts the machine from there. It also does not seem to matter if any partition on the disk is is mounted or not, the behaviour is always the same with 2 min. heavy activity before reboot.
System setup:
Sony Vaio VPZ13. Intel Core i5 M460, 4GB ram, 2x64GB SSD in RAID0 configuration via bios setting (a.k.a. fake raid), partitioned like:
windows boot
windows system
linux swap
linux "/"
linux "/home"
So it's a dual boot setup with Windows 7.
The raid array is assembled by mdadm, and I have mdadm_udev among my mkinitcpio.conf hooks (after blocks but before filesystems).

Since I have used Xubuntu without hassle for several years, I first thought the problem may be related to systemd reboot and something in my system setup. But I have tried the Fedora 17 live CD and rebooting there works as expected. So, since it works in one systemd distro, it should work with Arch as well.
Then I thought that it maybe had something to do with the raid-array, something along the lines of
https://bugzilla.redhat.com/show_bug.cgi?id=752593
https://bugzilla.redhat.com/show_bug.cgi?id=879327
But then I found the shutdown hook for mkinitcpio and now I see that the array is stopped and dissassembled. So thats not the problem either. (Or thats what I guess at least.)
Unfortunately I'm out of ideas. Any help would be grateful.
Last edited by wingbrant (2013-02-02 22:20:20)It turned out that the magic word for me was "reboot=pci" on the kernel command line. With that option set it works lika a charm The machine reboots nice and clean.

Windows 2008 R2 Hyper-V has really slow VMs disk access
Wondering if anyone can help? I have noticed in a couple of Windows Server 2008 R2 Hyper-V scenarios, that the VM guests are often very slow. Disk access is especially slow.
In one situation their was only a couple of guest VMs, and they were running of mirrored IDE HDDs. Performance improved significantly when I used two mirrored SSD hdds instead.
My other main situation is where the VHDs are stored on HP Lefthand P4300, over 2-nodes with 8 SATA hdds in each, using iSCSI.
So I ran a few tests with robocopy copying 4-6GB of files (mostly large) or whole VHDs (40GB or more), using HP4300 SATA, a newer HP 4330 SAS, a THECUS NAS with SATA hdds, and an SSD in a THECUS NAS, and local SAS mirrored hdds. All using iSCSI except
the local SAS hdds.
You can see from results that Guests run considerably slower than host. Any ideas?
Sample data (although not always same background conditions of load etc):
From within Guest direct iSCSI to same (from HP 4330): 34MB/s
From other Guest using VHD (from HP4300) to direct iSCSI (from HP4330): 14MB/s
From within Guest using VHD (from HP4330) to same: 9MB/s
From within Guest using VHD (from HP4300) to VHD (from HP4330): 11MB/s
From within Guest using VHD (from HP4330) to VHD (from HP4330): 19MB/s
From within Guest using VHD (from THECUS SSD) to same VHD (from THECUS SSD): 18MB/s
From within Guest using VHD (from HP4300) to VHD (from THECUS SSD): 13MB/s
From within Host from HP4300 iSCSI to HP4330 iSCSI: 12MB/s
From within Host using VHD (from THECUS SSD) to same VHD (from THECUS SSD): 40MB/s
From within Host from HP4330 iSCSI to same HP4330 iSCSI: 232MB/s & 132MB/s
From within Host from HP4330 iSCSI to HP4300 iSCSI: 40MB/s & 57MB/s
From within Host from HP4300 iSCSI to same HP4300 iSCSI: 26MB/s & 47MB/s
From within Host from HP4300 iSCSI to Guest VHD (from THECUS SATA): 15MB/sHi aucj,
I would suggest to use host level ISCSI connection then build VM on that ISCSI disk .
please add more Vcpu for that VM then try to copy again (shutdown the other VMs ,in that online VM from one folder to another folder ).
Hp4330 ISCSI connection is 1GB , right ?
If yes , it should be with max 100M/s with the single ISCSI connection .

Slow hard disk access --- still wonky
Hi,
Recently i've noticed that hard disk access has become very laggy, to the point
where it's driving me crazy.
For example, if i want to tab-complete through my directories, i have to wait a
few seconds each time. Similarly with saving files in vim, or just using
firefox, which seems to suffer frequent hangs while the disk is spinning.
I tried downgrading the kernel to 3.4.something, to no avail (it definitely used
to work just fine with the old kernels). I've also tried adding "commit=60" to
my fstab to reduce journalling access.
I ran bonnie++ and the following results came back:
Version 1.03e ------Sequential Output------ --Sequential Input- --Random-

t
which (by comparison with other results i've seen online) seem to indicate
there's nothing particularly wrong with the disk (it's a toshiba 7200rpm, i
think).
So i'm at a bit of a loss what to do next. I've attached my dmesg output. If
anyone has any suggestions, that would be awesome.

The lag tends to occur when first tabbing into a directory. On the second time
tabbing through things seem to be fast -- i guess that's cached somewhere.
editedit: i also tried switching back to initscripts, with no improvement, so i guess systemd is off the hook for the remaining problems

HD recycling leading to temporary freezes and directory damage
Hi all
I have an iMac 7, bought beginning of 2008.
I have had no problems with the computer until now, either windows or osx.
Over the past month I have been experiencing temporary freezes. This behavior in windows makes the computer freeze for about 2-4 minutes and then recovers. All the actions I make with the mouse during the freeze stack and resolve after the freeze. In OSX the freezes do not get in the minute range, just like 30 seconds long or so.
The problem usually extends to data corruption and failure to boot anymore. I have reinstalled OSX and windows many times now and the problems repeat. To the extent that that even during OS installation I get corruption. Verifying the disk just after installation report unfixable directory damage.
I am pretty convinced I have a hardware problem but I am trying to pinpoint it.
Things I have looked into:
Clear NVRAM & PRAM
Performed RAM test
Performed drive surface scans
Check S.M.A.R.T monitoring.
Graphics Tests
All things have shown negative results. Anyhow, my intuition (which may be off) leads me to a Hard Disk mechanical/heat problem. When the freezes occur, I clearly hear something, recycling, spinning off and then on. It could be any fan but I think it is the hard disk. What I don't know is if the recycle is consequence or cause of the failure.
The problem is getting worse in time. More frequent freezes and more frequent and evident data corruptions.
The reason I want to pinpoint the problem is to ease the support process. Apple warranty does not cover my iMac but by my country laws it must if the failure is not caused by miss-use. Somehow I expect to be a heavy administrative paperwork process because I am going to have to show somehow I have not done any miss-use before hand.
Other thing I am considering if its a hard drive problem, is opening the imac and replacing the HD myself, might be cheaper than the paperwork. Any suggestions on this??
Thanks for reading.HI,
*"Over the past month I have been experiencing temporary freezes."*
How much free drive space is there? Control or right click the MacintoshHD icon on your Desktop. Click "Get Info". Under the General tab you will see Capacity and Available. Make sure there is at least 10% available disk space, 15% is better.
Have you booted from your install disk, run Disk Utility?
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
If you cannot boot from your install disk, try booting in Safe Mode
And you could try the Apple Hardware Test

One other thing that can cause some strange behavior are custom icons, although I haven't heard it causing this particular problem... Could be worth a try, can't hurt.
Quit Safari, Open finder, go to your home directory > Library -> Safari ->Icons ... Drag the Icons folder to the trash. Re start Safari and a new folder will be automatically regenerated. You will loose all the custom Icons for sites visited, but they will be replaced the next time you hit those sites. -
Long system freeze on disk IO?
Hi everyone,
I have that problem for a few months now and am getting tired of it, and I have no idea what could be causing this issue =/
Since the last few months, the disk IO seems to stop working for a few minutes from time to time. Anything that tries to access the disk in that time just freeze as well, which seems to be everything except X. When it happens, it's usually when I hit save in a program, then the program hangs there and stops responding. Then I try to switch to another task, like the browser, then as soon as I requires disk access it freezes too! Then if I try to reopen any window the whole desktop freezes, just the mouse moving around and a few apps. After a while, say a minute or two, everything gets back to the normal.
All I get during the freezes is the hard disk led fully lit and nothing else. I don't seem to hear the disk actually doing anything too. The hard drive is not faulty, I changed it last week to replace my old one that did this too (I first thought it was because of my bad sectors on my disk, so I changed the disk).
Nothing really interesting from dmesg (remounts are probably during boot):
[ 13.908964] wlan0: associated

The "delay: ..." lines does not appear after the hang, I had one, did a dmesg, had another one, and nothing more to the logs.
Both stock and PF kernels do it. I did a fresh install after changing the drive, so most config files are stock too. Computer is a shitty System76 laptop (gazp5).
Funny enough, my Windows 8 install doesn't seem to suffer from this (but haven't used it for more than 2 hours, gaming OS only).
I'm really out of ideas, where should I look? Is there any test I can run to isolate the bug?
Last edited by Max-P (2012-12-18 03:16:28)Yet another bump!
Could it be related to USB? I have been playing around with JACK lately, and when used on my USB sound card, low latency (on both stock and pf kernel) made the OS crash (instead of the expected cracking sound).
But not only that, this morning it froze for ~20 seconds every minute or so, so I ran dmesg and got this

It stopped doing that when I unplugged my USB hard drive (which is powered off anyway, so it shouldn't interfere at all, doesn't it?). All seems fine for now, but until when? I know my JACK freeze printed a lot of SATA errors in dmesg "reset link 1,5 Gbps" or something like that (actually couldn't write the logs to an unavailable disk, obviously), it was like most of the peripherals were disconnected from the motherboard at the same time (USB, Keyboard, Mouse, SCSI/SATA, USB). I really think it could be related.
Here's /proc/interrupts, probably useless but I saw something about that when looking to fix my JACK issue to check the priorities or something (but really I don't care about JACK I was just playing around with it, but that + the above log seems to tell me something is wrong with USB and that could be the cause of all that crap)

i just bought a SSD hard disk..i plan to change my notebook hard disk to SSD..is it possible ? i'm trying to open the behind case that place Hard Disk it was hard to open..i'm suspecting it can change the hard disk to SSD ?
Hi:
I've successfully upgraded my Pavilion 15-n209TX notebook to SSD and let me tell you that it is not at all a walk in the park. You have to take out topcover, base enclosure, keyboard, battery, USB board and reach upto the motherboard to get access to the HDD. After that, it is just matter of replacing it with SSD.
It will definitely void warranty if you're going to do it as a major disassembly is needēd. Even if you're not under warranty, I would suggest you give the machine to local computer guys to do the upgradation.
The HP site is down at the moment and the Service manual can be downloaded 1 or 2 days later. Go through it properly.

Visruth

Firefox is a very busy piece of software. It's using large amounts of CPU time and disk access. It puts my usage at low priority, so I have to wait for some time to be able to use my pointer or keyboard. I don't know what it uses all that CPU and disk access time for, but it's of no use to me. It often takes off with massive use of resources when I'm not doing anything, and I may not have use of my pointer for several minutes. How can I shut down most of this so I can use the browser to get my work done. I just want to use the web site access part of the software, and drop all the extra. I don't want Firefox to be able to recover after a crash. I just want to browse with a minimum of interference from Firefox. I would think that this is the most commonly asked question.
Firefox consumes a lot of CPU resources

Time Capsule disk access SLOW! 2TB - Dual band
I have a Time Capsule (2TB, Dual Band, Firmare at 7.4.2)
Its been working like a dream, backing up 3 Macs for the last 8 months.
I also use it for connecting two or three other disks via USB and then making those accessible over the LAN, and there is also about 100GB of data on the Time capsule disk itself that i use as a dump for files so i can get to them from anywhere on my LAN.
Lately I started to notice EXTREMELY slow disk access, even when i am connected via ethernet (1000 base) - and equally when I am connected via wifi (n)
for example, copying over a 2Mb photo can take minutes when it should take seconds.
i've been trying to figure out whats going on here for a while and so i checked out the sizes of the backup files.. the sparseimages that time machine creates.
one of them was nearly 1TB, while another was around 500GB and the other was around 120GB
that plus my data meant there was only about 300GB free on the 2TB disk.
I have a feeling the slowness could be down to extreme fragmentation of the drive... ??
so i decided to dump the backup files and copy off my other data and do a erase of the disk and start again.. but get this.. i can't even delete the 1TB file ! I have been trying for about 3 days now and it just will not delete.. i get the Deleting msg box and it just sits there, literally ALL night...
i know it isn't just hanging on the Mac (10.6.4) because deleting the other two images also took a long time (but not this long!)
i can't just wipe the disk now because i can't get my other data off either.. I have tried copying it over the network and onto a USB disk connected directly to the Time Capsule, but 3 days later and i'm still copying files..
to put some context into this, I copied over 1.8Gb today and it took about 4 hours...
has anyone had this problem before?? what on earth is going on?? is it down to fragmentation, or something else?? the TC has been working fine up until a few weeks ago when i started to notice slow speed.
any ideas ?
thanks
Adamif anyone ever has this issue ....
it must have been EXTREME fragmentation. I bought another 2TB external disk, connected it to the TC, did a complete archive, which took around 24 hours... then i wiped the TC and put stuff back... it now works fine again... -
Error "NOTICE: [0] disk access failed" during guest domain network booting
Hi,
Could you please tell me what is the problem with my configuration?
I created guest domain on my T1000 server.
As a disk I used disk from disk array: /dev/dsk/c0t18d0
I added disk using commands:
# ldm add-vdsdev /dev/dsk/c0t18d0 vol1@primary-vds0
# ldm add-vdisk vdisk1 vol1@primary-vds0 myldom1
# ldm set-variable auto-boot\?=false myldom1
# ldm set-variable boot-device=/virtual-devices@100/channel-devices@200/disk@0 myldom1
Then I logged to guest domain and booted from network to install OS from JumpStart server:
{0} ok boot net - install
Boot device: /virtual-devices@100/channel-devices@200/network@0 File and args: - install

I am wondering about disk access I have a Toshiba 505-890 running Win-7
I notice that I am getting a disk access about every second as per the disk access light
coming on.
On my Win XP mach I don't get a light unless the computer is doing something for the most part.
Definitely not accessing every second.
I was wondering if this problem is endemic to win 7 or some Toshiba program I have not removed.?
If I put a clean install of win 7 will I still have this problem???This program is not giving me much info on what is doing the disk access.
I have attached a pic of what it comes up with.

USB Disk access "Extremely" Slow
I am unable to use my network disk essentially because the disk access write/read times are SO SLOW...I am better off running backups by connecting my disk directly to the compter. Does anyone else have this problem?
It took 5 Minutes to read my Music directory; connected directly via the same cable it takes seconds.
What gives?
Any help would be appreciated.I got my AE and Seagate FreeAgent Pro hard drive
yesturday and I have the exact same problem.
If I hook up the drive to the computer directly it is
very very fast.
If I hook it up to the AE it takes about 2 hours to
move a couple fils totaling 2 gigs over ETHERNET!
If I transfer the same files over the same network
between 2 computers the speed is much much faster.
Is this normal or some nasty firmware bug. It almost
feels like the AE is using USB 1.0 for some reason.
You guys are funny. How about checking out the specs of USB 2.0 and 802.11g/n?
Go here:
http://en.wikipedia.org/wiki/802.11g#802.11g
and here:
http://en.wikipedia.org/wiki/USB_2.0
Firewire vs. USB tests are here:
http://www.g4tv.com/techtvvault/features/39129/USB20_Versus_FireWirepg3.html
802.11g:
Release Date Op. Frequency Data Rate (Typ) Data Rate (Max) Range (Indoor)
June 2003 2.4 GHz 19 Mbit/s 54 Mbit/s ~35 meters
802.11n:
Release Date Op. Frequency Data Rate (Typ) Data Rate (Max) Range (Indoor)
Mid 2008 5 GHz and/or 2.4 GHz 74 Mbit/s 248 Mbit/s (2 stream) ~70 meters
Bottom line: 802.11n typical is 74Mbps, 802.11g typical is 19Mbps. USB 2.0 typical is 50Mbps.
On the average, you should expect your speed to drop by over 50% when connecting the USB drive to AESB using an 802.11g device. If your device is 802.11n, then you should have pretty much similar performance.
Now, if you increase the distance from your base station, or you put walls in between, the performance of 802.11g will go down "dramatically", all the way to 2-3Mbps, easy. Not so for 802.11n, which behaves much better at longer distances. -
Extremely slow disk access iMac5.1
Hello, my daughter is having problems with her computer. She has a Mac5.1 ( intel ) running 10.4.11.
In the process of trying to determine the problem, I installed Xbench on her computer. The numbers for the disk access category are dismal, all others (although low) appear normal.
This disk values are:
Sequential 0.03
Uncached Write 0.01 0.01 MB/sec [4K blocks]
Uncached Write 0.17 0.10 MB/sec [256K blocks]
Uncached Read 60.40 17.68 MB/sec[4K blocks]

Uncached Read 63.58 17.68 MB/sec[4K blocks]
Uncached Read 99.67 43.59 MN/sec[256K blocks
Aparently sequential access is much worse that random access however Apple utilities as well as Onyx claims that the disk is fine. However the computer is nearly unusable. What else can I try? I ran an fsck on the disk, I also caused the write permissions to be corrected. I am running out of ideas.
BTW her disk is a WDC WD160JS-40TGB0. Out of 148 Gig, 110 are used and about 40 are free.
Any Ideas? Any help is greatly appreciated.How much RAM does the iMac have and how many Applications are running concurrently or set to open at login?
40GB should be ample free space for V-RAM, but it could definitely get bogged down if there is to little RAM for the users needs.
Sometimes one will inadvertently set a bunch of stuff to automatically open at login. Go to: Apple > System Preferences > Accounts > Login Items and remove any unnecessary Application automatically set to open at login-in and then restart the computer.
Then again it could be that the HD is just suffering from age, if it has been thrashed because of continual page outs due to the lack of system memory. Because my Earlier 2006 Mac4,1 with 2GB of RAM that I upgraded (for space reasons) to a WD 320GB Hard Drive in 2009 is getting:
