search for: vnode

...t and I''m leaking them somehow? On the other hand when I unload ZFS kernel module, FreeBSD''s kernel reports any memory leaks - they exist, but are much, much smaller. There is also quite a lot of znodes, which I''d also like to be able to free and not sure how. In Solaris vnode''s life end in VOP_INACTIVE() routine, but znode if kept around. In FreeBSD VOP_INACTIVE() means "puts the vnode onto free vnodes list" and when we want to use this vnode for different file system VOP_RECLAIM() is called and VOP_RECLAIM() will be a good place to free znode as well...

...ain. I can reliably get the box in to this state by doing 'find /'. I do have a lot of files on the disk, and a things like squid and postgres that do a lot of file i/o, but I don't recall this happening before this week. I don't find anything in 'tuning' about bumping up vnodes, but I do see sporadic reports on a google group search - searching for 'ffsvgt'. Anybody run into this before? - Mike H.

i need to get inodeno on ZFS and i am not able to find how to find it in kernel at vfs layer. i have vnode pointer and i am doing VTOZ to get znode but printing z_id from znode pointer gives me deadbeef(unitialized) , can somebody point me how to get that? i looked at zfs_getattr code and it does similar thing which i am doing but its able to get me inode no in getattribute structure(node id), that...

Hi, my FreeBSD-9/stable machine (FreeBSD freebsd-tower.goebo.site 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #2 r241044M: Sat Sep 29 12:52:01 CEST 2012 lbo@freebsd-tower.goebo.site:/usr/obj/usr/src/sys/GENERIC i386) crashes reproducibly when rsync-ing files to an NFSv4 share on the FreeBSD machine. The crash makes the system reboot. The crash creates files in /var/crash which may be obtained

...ocess try to muck with? It is a root owned file, and it is important that it want to act on it. Security problem, or benign problem? Who knows without being able to know what the file is. A look at the source code implies that the "request 256" means that the web process tried to read the vnode numbered 256. Is that accurate? If it is, how do I go about associating vnode numbers to files, so I have a hope of troubleshooting these errors. Searching seems to turn up no tool or easy way to get this vnode -> file information. Help! Jeff

I''m trying to debug a problem that requires I print the dirty pages (v_pages) list. Any suggestions? This message posted from opensolaris.org

Two machines (NFS Server: running ZFS / Client: disk-less), both are running FreeBSD r253506. The NFS client starts to deadlock processes within a few hours. It usually gets worse from there on. The processes stay in "D" state. I haven't been able to reproduce it when I want it to happen. I only have to wait a few hours until the deadlocks occur when traffic to the client machine

I have a script where I can freely reference struct nameidata*, struct vnode*, etc. on Snow Leopard. How does DTrace know about these data types? I understand things like #pragma D depends_on library darwin.d where darwin.d has typedefs. I can''t find definitions of nameidata and vnode in any D scripts, though. How does it work?

...baseline system (those will be patched by the MFC) which deal with advisory locks. As such the impact should not cause many people problems. The work that will be MFCed fixes issues with filesystem advisory locks, and moves the advisory locks list from filesystem-private data structures into the vnode structure. The MFC will be done by Kostantin Belousov some time this coming Friday (August 1st, 2008) if you have concerns and want to watch for it.
