TS-419P smbd and flush-9:0 acting up
Hi all
Can't really figure out what's bugging my NAS, hopefully someone here can.
When running donwload station or transmission (haven't tried other apps) it keeps loosing connections, and flush-9:0 slowly eats up the CPU, while it's almost unreachable via mapped networkdrives (from a Win7), Squeezebox, HDTW Live and other mediastreamers.
If I kill writing activity on the NAS, the above stated seems to run much smoother
On the other hand, if I try and copy a file from the Win7 box, flush-9:0 slowly eats up the CPU again, and after a while I see the SMBD process taking 99.9% of the cpu, and the NAS is virtually inaccessible and the filecopy dies
All the while, the administrations panel (via http) is working as smoothly as a newly installed NAS and so is any kind of SSH access ?!
Any ideas are welcome

Re: TS-419P smbd and flush-9:0 acting up
I encounter similar problem. After trying to copy a bunch of files from Windows 7, flush-9:0 appeared, and the smbd eats up all the cpu in my TS-210. I haven't changed anything on my NAS, recently I've only add a 2TB external USBdisk, I don't know whether it's related or not. Anyone could advise? Thanks.

Re: TS-419P smbd and flush-9:0 acting up
Same identical problem for me.
Other observations are
* that I get "SAMBA --- Login Fail" in the system connection log at the very same time as the flush and smbd starts to spin out of control.
* The process that consumes 99% of the CPU is the only one running with an guest account "guest 4272 R /usr/local/samba/sbin/smbd -l /var/log -D -s /etc/con"
HW: 419P with 4*SAMSUNG HD203WI in RAID5, EXT4
FW: 3.3.9 Build 0120T
/Gixxer

Re: TS-419P smbd and flush-9:0 acting up
I am also experience similar problems on my TS-410.
It worked flawlessly since I bought it 3-4 month ago until last week.
Flush-9:0 and SMBD eats up the CPU and I can't write and barely read anything to it.
All 4 drives in the NAS is officially recommended 1TB drives by QNAP (Seagate ST31000528AS).
Raid5 with EXT4 which I now rebuilt to EXT3, no change to behavior.
NFS and SMB both gives the same behavior.
Tried both different firmwares from 3.3 and 3.4, with no effect.
Any official response to this from QNAP would be greatly appreciated.
Is it possible that the CPU used is to slow when the data-amount gets to high and cant handle all the network and disk-access?
The bigger models use 1.2 - 1.8 GHz Atom while TS-410 and smaller uses an 800 MHz Marvel.

There are no [flush-x:y] processes on TS-x09.joelang1699 wrote:This issue just appeared for me today. Cant understand why.
All ARM-based NAS users should avoid operating their QNAP NAS on v3.4.0...v3.4.2 and upgrade to v.3.4.3 instead using the manual firmware upgrade process from the Linux NAS as shown here: http://wiki.qnap.com/wiki/Manually_Updating_Firmware .

Re: TS-419P smbd and flush-9:0 acting up
I dont have any TS-X09 models, only the TS-419P. However I will try a manual update to 3.4.3 from 3.4.2 to see if it makes any difference. flush-9:0 is there as im looking at it right now.schumaku wrote:There are no [flush-x:y] processes on TS-x09.joelang1699 wrote:This issue just appeared for me today.

Just updated manually, still as bad as before. Infact the NAS is almost unuseable.

Re: TS-419P smbd and flush-9:0 acting up
Potentially an issue with the file system, the RAID, or the disks - and unable to read/write the storage in time?

Re: TS-419P smbd and flush-9:0 acting up
Same here, recently reported to Qnap as follows, they have been good and want to remotely connect to investigate...., I would just prefer them to fix the problem as I am obviously not alone.. My system is Qnap 639 with 6x2TB Seagate HDD, Firmware 3.4.3 Build 0520T
Having continous problems with being unable to write to my shares, read works perfectly but attempting to write a large file to my shares in SMB, NFS of FTP will fail 4 out of 5 times (it times out "share no longer available" ) EXT4 FS with write cache enabled. During the problem all drives flash as it was writting with flush-9:0 process taking processor time, smbd does nothing, the client PC starts new connection causing multiple smbd each idling waiting for the kernel to allow it to access..., same time unable to do ls /share/MD0_DATA in shell - it locks up.

Thanks shumaku..., lots of BD-ISO's, plenty of photos..., 9.1TB of data in all.schumaku wrote:Many mediaum ot large size files on the storage volume?astropolak wrote:same time unable to do ls /share/MD0_DATA in shell - it locks up.
Have played with live Kernel parameters, achieved no more lockups at the cost of transfer speed. Still get 5-10 second breaks when the NAS will not accept any new data, Flush-9:0 writing away then the NAS resumes as nothing had happened...

Re: TS-419P smbd and flush-9:0 acting up
Is the kournald process going to DW state? D would be "Uninterruptible sleep" (typically waiting for I/O), W would be "wait for memory" (paging).

Re: TS-419P smbd and flush-9:0 acting up
Same problem!
TS-419P, dead slow speed to write, via FTP, or AFP, or SMBD either!
System: TS-419P, 2T x4 as RAID5, has been Working perfectly for more than half years!
This problem came recently.
