Description

Dell R720 servers won't shutdown or reboot to prom, hanging on the usual "syncing disks, rebooting...".

I've no idea how to investigate this, feel free to ask for commands run on this machine.

Oh it may be interesting to add that on rare occasion it can work, about one time out of 10'.
Hanging reboots are both user-initiated or after a fault and core dumping.

I have an R720 on which this succeeds without difficulty; what is the configuration of yours?

Here's what I have :
  • R720xd with BIOS 1.6.0
  • 192G RAM (12 * 16G)
  • two 8 core Intel E5-2660
  • LSI 2308 cards but I've found it is not the issue

Are you using BIOS or UEFI boot ?

I'm seeing the same. Are you using OmniOS? If so what release?
Second, do you have other zpools than your root pool? If so could you zpool export [pool] them before rebooting. That seemed to to the trick for me. I assume that you've nothing shared from your root pool. Just a plain install and perhaps a few snapshots but nothing more.

This is either OmniOS 151006p or after an upgrade to bloody, it will do the same.
Actually I only have the root pool and nothing is shared, the first time I've seen this was minutes after installing the first 720xd. There's something interesting in your experience because now I realize the only reboots that did complete, and that's mostly user-initiated and not after a crash, were I believe when I did absolutely nothing with the server. Uptime probably was less than 5 minutes...
Still I don't get it, in my understanding the message printed on screen appears so late in the process a driver should not make it stall.

We're seeing the same issue on a SuperMicro 826 (-9). The commonality is we use an LSI 2308. Perhaps the issue lies there?

I have a similar issue here with OpenIndiana (oi_151a8) on a Supermicro X7SPA-HF board. Interestingly reboots work fine but the machine hangs at "syncing file systems... done" when performing a shutdown. I tried various shutdown commands (shutdown, poweroff, straight init,...) but found no difference there.

This is a tiny Atom board without an LSI HBA. :-) Disks are attached to the onboard SATA ports. Chipset is ICH9R, BIOS 1.2a. Default BIOS options are selected.
