i'm also seeing the write cache disabled error and it was working fine previously. ds1512+ here with wd green drives. anyone found a solution?

This is getting ridiculous. I got myself large 2TB green disks with 64MB cache to cope with the slower speed, and now Synology disables this cache, without any valid reason, resulting is less performance. I will trade in my Synology for a QNAP pretty soon now.

Have fun with your Qnap and their file system bug.
http://forum.qnap.com/viewtopic.php?f=2 ... &start=360

I was just about to buy a Qnap when I discovered the 25 page thread on their forums about this bug that slows the NAS down as it fills up. From my brief read of the thread, it seems this has been an ongoing problem with no guarenteed end in site.

I'm glad I bought a DS1512+, although I read about the problems with the WD drives and bought Seagate drives that have the cache enabled.

Same here with my 211j. I had the box checked and working for both of my WD green drives previously, but now they are checked and grayed out with the same red font message noted above.
Performed a LAN Speed Test and compared with prior results. Had about a 2% drop in write throughput performance and had about a 2% increase in read performance. I'd say plus or minus 2% is probably w/in the error bound of the test so I can't say that there's much of a difference in performance. But, this is a simple test with one large (5GB) file and my sense is that with a more intensive random read/write test suite will have a different result. Since I use my NAS for backup and as a media server to stream videos to TV/media players, I don't think I will see any performance issues. We shall see....

If you want have cache enabled, you have to edit scemd.xml file and delete "cache off" part at the end. It works fine for me.

Updating to this on my DS1511+ seems to have disabled the permissions for any non admin users, trying to copy files to folders, i have reset their permissions, but still returns the error, they do not have enough privilege, even the same when i create new ones,

Very frustating, has anyone got any ideas, it was fine on the last build.

Ok, edit.

I used to have disable file downloading ticked all the time and people could still copy from folder to folder, now unless i have that Disabled(unticked and not ticked) they cannot copy, before they could not copy if Disable modification of existing was ticked.

Sorry this is confusing, my understanding was disable downloading, stopped people from downloading, not copy from one folder in the Dsm to another, e.g. a usb drive.

If you have made a configuration backup from the previous DSM version,
put it back and recheck after reboot.

Will give that a try thanks, as the guest account seems to Partially stopped working as well, i say partially as some folders load and others give an error, even though they all have the same persmissions, and work fine with another user and password.

I tried, looks like it has now reverted to a Lion 10.7 issue. user and password connect fine.

Guest account does not connect now i did notice after i upgraded, that the Mac File service was disabled, i enabled it.

Guest could connect, to "folder 1,folder 2, and Folder 3 fine before without password

Guest before would i redid the settings as suggested, would connect to "new folder" but not to previous folder 1,2 and 3, returns with error : original item cannot be found when i try to mount them using either afp, or smb.

Its odd, i mean its not a big deal as i just created a user password, for the user that was using the guest account. I have tried everything i could think of, cleared all the cache's from the mac's turned off and back on all the switches and routers. Enabled and disable the guest account, changed and unchanged permissions etc.

Never ever has this issue since DSM 3.0 or even the jump to lion, which i read lots of people do.

Ho hum, any help from anyone would be grateful, more because its annoying than not working, as it should

Well. I did some testing. I decided to take the plunge and modify the scemd.xml to re-enable the disk cache. Before I did, I did some measurements, and also afterwards. I did 2 tests: one with the 11GB \windows\installer directory, and one with a 7GB file.

Disk cache disabled:
Installer from PC to NAS: 67MB/sec
Large file from PC to NAS: 90.7MB/sec
Installer from NAS to PC: 53MB/sec
Large file from NAS to PC: 60MB/sec


Disk cache enabled:
Installer from PC to NAS: 67MB/sec
Large file from PC to NAS: 90.4MB/sec
Installer from NAS to PC: 51MB/sec
Large file from NAS to PC: 63MB/sec

So, no significant differences. It seems the Synology onboard memory handles most caching on reading and writing. The disk cache doesn't make the write speeds any faster.

(And yes, the read speeds are way tooo slow and should approach 90MB/sec. I already contacted Synology on this.)

HP 5440 printer no longer works.... after upgrade. It will print a test page from the control panel, but after hours of removing,reinstalling and cussing... it still wont print from any of my pc's

Is there a formal place to submit bugs like this?

On my DS211 the write cache is still usable: I can enable or disable it without problem.
