Greetings, Is there a known bug in the kernel related to NFSv4 in joyent_20141113T164921Z ? My production system was rock stable until I've upgraded the platform to the 20141113T164921Z last week. Today, it has crashed with kernel panic indication on nfs4. I'm not an expert in the kernel dump analysis, but a quick look with mdb showed the output I digested below.
A virtual zone was mounting NFS from a NetApp filer. The system looks stable now, but I'd like to avoid a possibility of such crash again. Any suggestions? Thanks, Alexei BAD TRAP: type=e (#pf Page fault) rp=ffffff007dd6e940 addr=1000008e occurred in module "genunix" due to an illegal access to a user address dump content: kernel pages only vnevent_rename_src+0x39(10000016, ffffff25e5506440, ffffff21ecc13480, 0) nfs4rename+0x344(ffffff25e5506440, ffffff21ecc13480, ffffff25e5506440, ffffff21ff654dc0, ffffff24403c2288, 0) nfs4_rename+0xae(ffffff25e5506440, ffffff21ecc13480, ffffff25e5506440, ffffff21ff654dc0, ffffff24403c2288, 0) fop_rename+0x68(ffffff25e5506440, ffffff21ecc13480, ffffff25e5506440, ffffff21ff654dc0, ffffff24403c2288, 0) vn_renameat+0x3ff(0, 82007f8, 0, 8278248, 0) renameat+0xdc(ffd19553, 82007f8, ffd19553, 8278248) rename+0x22(82007f8, 8278248) _sys_sysenter_post_swapgs+0x153() ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
