Feb 25, 2020  MultiTask - Archiver 2 is geared to take full advantage of your Mac, allowing you to do a whole lot more at the same time. And it's remarkably easy to do! And it's remarkably easy to do! By simply dragging in more archives, Archiver will extract them for.

For now I can stop the crashes by disabling icloud photos library, which is trying to download 150GB of my orginial phots from icloud onto my iscsi disk.In the meanwhile, listening to iTunes which has the library on the same disk, doesn't cause any crashes (for several hours now).The disk has been mounted for nearly 24 hours now without crashes.So it seems it's related to (heavy?) writes or os x photos library.I have rsynced about 4GB to the iscsi disk without crashes. Will do some more tests later on. I just want to chime in to confirm I'm having a similar problem. It's similar, not identical, because I'm using it on a Mac with macOS Sierra, and the Synology DS216j NAS. The latest beta resolve my original issue of not being able to mount and format the target, as well as re-mounting after waking from sleep. It works well with small to medium size files, but when I try to move an approximately 150GB iPhoto library from the main drive to the iSCSI target, I get the same hard crash and reboot describe. It really only does seem to happen during large file transfers.The main reason for trying to use this feature was to be able to offload the library to the NAS, so I've been sort of waiting in the wings to see if others are experiencing the same troubles.

Some more observations:. The console app contains lots of crash dumps from around the same time were the I get the kernel panics. I have attached those (there has been 2 kernel panics in the same timeframe). Up to the first crash, I tried to capture some system information (like netstat, top, iostat, ping)There was nothing scary to see. Netstat reports the connection is established the whole time and performance seems to be stable all the way. There's no indication of 'something building up' towards the kernel panic. I discovered that there are a lot of 'stuck' processes on my mac mini in general compared to my macbook.

From my understanding these are like uninterruptable sleeps which could be waiting for I/O.However, even though the number seems high to me (compared to my macbook which tops at 1 stuck process at a time), the number looks stable between 10-20 towards the kernel panik. Right now with icloud photosharing downloads set on pause the amount of stuck processes is about 10.Also, the processes which are stuck aren't all related to the iscsi disk (i think):home: root# ps aux grep ' U' root 5203 0.0 0.1 24 s002 U 8:58PM 0:00.03 sudo -i kroeger 5121 0.0 0.2 252??

I tried to reproduce the issue with dd and writing various files in 4 simultaneous threads. At some point the dd processes became unresponsive.

At the end, I wasn't able to get the system to kernel panic, but instead the disk got umounted / logged off. When I tried to logon again, I couldn't (I think i got a connection error) - when I tried to query the disk locally from the linux box I couldn't get a connection either. So I killed tgtd and restarted it. Afterwards I could logon from mac os again and mount the disk. However, the previous dd processes were still hanging (I suppose this is normal, after the iscsi target has crashed).The only message i got from the tgtd process was:Feb 22 23:11:46 nas tgtd: tgtd: iscsitaskrxstart(1794) Unknown op 2a. Normally I don't see anything in the logs on the linux box when os x is crashing. And usually the tgtd process doesn't need to be restarted.

However - today at the second crash, I got:Feb 23 15:51:19 nas tgtd: tgtd: connclose(140) Forcing release of tx task 0x205ad10 3659d720 1I think I will have to try a newer version of tgtd. The laptop is not set to go sleep, nor is it set to put drives to sleep (the main drive is SSD) so no spin down.the fact that it goes for well over an hour before crashing tells me it's not really related to sleep.

So the log I sent is without setting the laptop to sleep.The only thing that might have something to do with it (and this is just a shot in the dark) is that Photos libraries are a lot of hard links (I don't know the exact term) and the OS is supposed to handle copying actual files when you move the libraries. I don't know if that could have anything to do with it, but I thought I'd mention seeing how the other user's issue is also related to Photos. Thanks - I missed your comment regarding sleep earlier. I'm not sure what you mean by 'hard link' (symbolic links?).

Filesystem-level objects should be completely transparent to iSCSI - it doesn't care what you're transferring or how, it just processes low-level hard disk commands. The logs show that the kernel extension crashes when the destructor for a component is called. This occurred when the connection was being taken down. That's why I asked about sleep, and earlier about whether the connection is interrupted at all. I will try to reproduce this. I've tried to mitigate disconnection at the network level as much as I could, although there's still a possible point of failure at the switch.

The laptop has a battery, obviously, and NAS is on a UPS, but the switch gear could still be affected by some power fluctuation. I should probably get a small UPS for that too.As for the Photos library, I'm pretty sure they are 'hard links', not symbolic links (I had to look it up, as I couldn't remember the details). Looking forward to what you find. If I do get a UPS for the switch gear, I'll do another test.

In each instance the OS no longer crashed/panicked, but the copy still did stop after about 30GBs. I've not had time to dig up a crash report, but the error the Finder gives is that it was unable to to unmount the drive correctly which is weird as it didn't need unmounting, obviously. I'll attempt it again to try and capture the error and crash log and see if a 3rd time gives the same consistent result.

Hello Nareg,thank you so much for getting back to this. I apologize for not revisiting this sooner. I will definitely give the new version a try and let you know the results, but I'll tell you a bit more of what happened with my last attempt, and why I haven't gotten back with a response yet.After the last crash, there were another Sierra OS update. So I had finished that, uninstalled iSCSI and re-installed it.

Then I turned off TimeMachine backups and re-started the large copy. This time the copy lasted much, much longer.about 100GBs in, but then it crashed in the same way. The Synology NAS I'm using is the TimeMachine target as well as the iSCSI target. Obviously, they are on separate partitions and volumes. I'm not sure if it has anything to do with it, but maybe that scenario helps with any other possible edge cases you'll encounter.After all that, I was hoping to attempt the whole thing once again. Every single attempt so far has been using the MacBook's wireless interface.

Every piece of network and hardware device is on UPS so I'm confident on the hardware, but the wireless is the last 'magic' that could be an issue on long transfers. There are no wireless issues in general with the network. So I was hoping to borrow/buy a USB ethernet adapter, turn off TimeMachine, re-install iSCSI and try the whole thing again, but got bogged down with the kids and the fact that the wife (who's computer it is) can't seem be without her laptop long enough to run this test. HehAnyway.I'll make this happen and let you know. Thanks again! Well.mostly.I un-installed beta 5 and installed beta 6.

I turned off TimeMachine and tried again. It crashed again after about 3 hours.At this point the last thing I could try was to rule out the wireless connection. I borrowed a USB Ethernet adapter (it's a MacBook Air.has no wired Ethernet port) and plugged it in. Not only did this work, and copied over the entire 135GB library to the iSCSI target, but it did it in 32 minutes, rather than the projected 14 hours!So the wired Ethernet helped in two ways. If there is a problem with iSCSIInitiator (I'm kind of thinking there isn't) it's definitely not size-based, but time based. I suspect this is unlikely.

Having plugged in the wired Ethernet showed me that the MacBook wireless was going way slower than it should. It turns out that my router being set to serve mixed G and N causes the MacBook to connect at G speeds only. Since I no longer have the legacy devices that used G, I simply switched the router to N only. I tried doing the transfer again and this time the projected time was 7.5 hours instead of 14, so that's twice the speed. It's quite possible this would have worked, but I stopped it as I didn't want to mess around with it any further.In short.it worked. Wired Ethernet dealt with the 135GB archive transfer without any troubles.

The Photos library can be accessed like any other library in Photos for MacOS Sierra and it's pretty darn fast all things considered.Many thanks, Nareg. Let me know if you need anything else. Limited time, but happy to help.
