Well, but this is not the case. I can access all shares on all servers BUT the share of the flash drive on SOME servers. And the error message (permission denied when changing directory to /boot) indicates a permission problem with the flash drive's share / mount point.

The servers are all joined to Active Directory. I just tested the connection from a Linux box: root@cineplex01:~# mount -t cifs //cineplex07.celtic-ads.xxxx.xxxx/flash /07 -o username=imrevo,password=xxxx,domain=celtic-ads root@cineplex01:~# mount -t cifs //cineplex08.celtic-ads.xxxx.xxxx/flash /08 -o username=imrevo,password=xxxx,domain=celtic-ads mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg) So the issue is not related to Windows or "the client" but to the server. I will remove one of the servers from AD, add a local user and try the connection again. I'll keep you posted. [...some time later: ...] Tests revealed: As soon as I set the SMB Settings to "Enable SMB: Yes (Workgroup)", I can access the SMB share FLASH with the local user I created on Unraid. When the setting is "Yes (Active Directory)", I cannot connect to the share with any user, AD or local: Permission denied. Unjoins, rejoins and reboots did not help.

Hi, thanks for your input, but Settings/SMB "Enhanced macOS interoperability:" was already set to "No" and enabling disk shares did not help either. Some more information: I can see the FLASH share via network and can even mount it, but I cannot access it ("access denied" in Windows) on ~50% of the Unraid servers All 11 servers have the same SMB / disk / flash share settings All servers are on Unraid 6.9.2

Good morning, I got 11 Unraid servers and on about 50% of them I am unable to access the flash drive via SMB share. The following error message repeats ~20 times in /var/log/syslog: smbd[20582]: [2021/09/24 08:58:06.709121, 0] ../../source3/smbd/service.c:168(chdir_current_service) smbd[20582]: chdir_current_service: vfs_ChDir(/boot) failed: Permission denied.

As the error message is about switching to /boot, I already checked: the share settings for the flash drive sharing / unsharing works without errors, all servers have the same settings permissions of /boot: identical on all servers (drwx, root:root) mtab shows the same entry for /boot on all servers: /dev/sda1 /boot vfat rw,noatime,nodiratime,flush,dmask=77,fmask=177,shortname=mixed 0 0 Any idea where to look next? bye Volker cineplex02-diagnostics-20210924-0900.zip

Hi, Yes, I even 'grep'ed the logs of my mailservers and limetech is in my spamfilter's whitelist ;-) My last orders went very smooth so I am really surprised about the delay this time. bye Volker

Good morning, anybody here? Still no reaction (and no key) so far. Anything happened to Tom? with kind regards Volker Imre Imre IT-Services

Good morning, I purchased a Plus-Keypack on 2014-05-06 but received no key yet. Also sent an email with transaction information via contact form, no reply yet. with kind regards Volker Imre Imre IT-Services

Yes. Resulted in quite an increase in transfer speed, mainly when copying data to the microserver. Reading was fast enough without the "fix".

...and after applying that cpufreq-"fix", I wonder why so many people waste so much money on Synology, QNap and Buffalo :-) The "fix" for the N54L (from some post in this forum) and maybe as well for the N36L / N40L is adding these lines to the go script: echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold & logger Go Script - ondemand up_threshold set to 50 echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor & logger Go Script - ondemand sampling_down_factor set to 50 and of course you should execute these 2 lines once (or reboot, whatever you prefer). That made the benchmark for "writing to the unRaid with cache disk" look like this: Seq. Write Speed: 95.4 MByte/sec Seq. Read Speed: 98.7 MByte/sec Without the fix: Seq. Write Speed: 54.3 MByte/sec Seq. Read Speed: 97.3 MByte/sec The original value for "up_threshold" was "95" on the N54L.... way too high, if you ask me (and the benchmarks :-) ). cu Volker

As promised, find some benchmarks attached: without cache disk, with Samsung 750GB as cache disk, with Samsung SSD as cache disk. I am very glad about these results and I'm a little bit surprised that it doesn't really matter if you use a ssd as cache disk or an old Samsung HD753LJ when writing to the raid. Both are fine for increasing the write speed. N54L-Benchmarks.zip

Good evening, short update: preclearing is done, now it's sync'ing parity at ~170MB/sec, see attached image. Some hdparm benchmarks: /dev/sdb: Timing cached reads: 3236 MB in 2.00 seconds = 1618.20 MB/sec Timing buffered disk reads: 454 MB in 3.01 seconds = 150.96 MB/sec /dev/sdc: Timing cached reads: 3198 MB in 2.00 seconds = 1598.90 MB/sec Timing buffered disk reads: 464 MB in 3.01 seconds = 154.39 MB/sec /dev/sdd: Timing cached reads: 3188 MB in 2.00 seconds = 1594.39 MB/sec Timing buffered disk reads: 468 MB in 3.01 seconds = 155.50 MB/sec /dev/sde: Timing cached reads: 3270 MB in 2.00 seconds = 1635.11 MB/sec Timing buffered disk reads: 452 MB in 3.02 seconds = 149.88 MB/sec more to come.... @neilt0: 7th drive? Where do you connect that one? cu

Good evening, currently, I'm building my first unRaid-Server and I want to share my thoughts and experiences. Hardware: - N54L HP Microserver, 4GB RAM, No-HDD, with DVD-RW, Model #708245-425 - 4 x 4TB ST4000DM000 - Bios-Mod for full speed at all 6 Sata-Ports Further additions, already bought but not installed yet: - Samsung 840 EVO 120GB as cache disk - another 4TB ST4000DM000 as manual "hotspare" - Raidsonic ICY BOX IB-172SK-Bas replacement for the DVD-RW drive unRaid 5.0 is placed at a SanDisk 8GB stick plugged into the internal(!) motherboard usb slot of the N54L, no problems with booting or sharing. The bios settings have been changed according to the link above and, VERY IMPORTANT, disk caching has been enabled in the bios (only do that if you have some form of ups!). Changed the parity creation from 38MB/sec to 80MB/sec @ the test setup with 3 Samsung HD753LJ. I already added unMenu, openssh and some other plugins, no big deal but worth mentioning as it was a simple click-and-click procedure and not what one might expect from a linux system :-) I started the pre-clear-Script about 28 hours ago, for all four 4TB discs at once (4 telnet sessions) and here's the main reason for starting this thread: - none of the 4 disks ever went above 35C - the pre-read and the post-read speeds are ~140MB/sec per disc - the N54L is still very silent (located ~50 cm to the right of my head at the moment) The pre-clear script will be finished tomorrow and then I will do some benchmarking that will be published here, of course. After 4xN40L with Windows 2012 and StarWind iSCSI as data pool for my two Dell servers running ESXi 5, this N54L is my first server running unRaid. The tests with the free license and my 3 Samsung HD753LJ were very successful and promising. One question may be permitted: Is there really no possibility to define a hotspare disk that jumps in automatically in case of a hard disk failure? Of course, this disk has to match the largest disk in the array, i.e. the parity disk. Any plugin, perhaps? We are talking about data, maybe valuable data and this data should be protected best effort. cu Volker
