similar to: printing vnode page list

Hi. I would like to print out a field of a vnode, but the argument to the function is of type vnode_t **. If I set "this->vpp" to arg2 in an entry function to zfs_lookup(), I''d like to retrieve the value of one of the fields of *(this->vpp) in the return function. Something like the below (but the syntax below is not right): printf("zfs_lookup:

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

I think I've read somewhere about panic during early root mount, fsck etc.. Perhaps this might be related: Full dmesg: http://people.freebsd.org/~ariff/misc/dmesg.boot.amd64 [....] acquiring duplicate lock of same type: "vnode interlock" 1st vnode interlock @ kern/vfs_vnops.c:791 2nd vnode interlock @ kern/vfs_subr.c:2018 KDB: stack backtrace: witness_checkorder() at

I woke up to a frozen box this morning - it froze up a few more times before I got a handle on it. Basically, the box runs idle but refuses to do disk IO, or does it -very- slowly. Top shows processes stuck in 'ffsvget', 'inode', and 'vlruwk' state. I can get the box responsive again by setting sysctl kern.maxvnods=100000. It starts up with kern.maxnodes=36079. I

So I realize this is somewhat stupid, and I''ve actually gotten myself out of kmdb to kill my dtrace script but this has happened in the past and I''m wondering if there''s any better way around it than hitting :c a bunch of times. Say you set a breakpoint() to fire in a common function. This will drop you into kmdb where you can do some debugging, you take a look around

Good afternoon everybody, I'm quite new in functions optimization on R and, whereas I've read lot's of function descriptions, I'm not sure of the correct settings for function like "optimx" and "nlminb". I'd like to minimize my parameters and the loglikelihood result of the function. My parameters are a mean distance of dispersion and a proportion of

Hi, To get my understanding of zfs data structures correct, I need to trace znode_t from given dnode_t. I came up with following trace, is this correct? dnote_t->dn_bonus->db_user_ptr points to corresponding znode_t Is there any other(better) way to trace znode_t from dnode_t? Cheers, -Atul

I''ve been testing ZFS since it came out on b27 and this week I BFUed to b30. I''ve seen two problems, one I''ll call minor and the other major. The hardware is a Dell PowerEdge 2600 with 2 3.2GHz Xeons, 2GB memory and a perc3 controller. I have created a filesystem for over 1000 users on it and take hourly snapshots, which destroy the one from 24 hours ago, except the

Hi, I have setup an old Compaq Proliant DL580 with 2 xeon @700MHz 2Gb RAM two SmartArray 5300 controllers and 12 drives in an array enclosure. I am running the latest opensolaris update bfu''ed from binaries since I could not build from source. I am controlling the drives with the cpqary3 driver (Solaris 10) from HP. Initially the array had 7 drives and I created a raidz zfs pool

Hi, Since almost all operations in the FUSE low-level API identify files by inode number, I''ve been using zfs_zget() to get the corresponding znode/vnode in order to call the corresponding VFS function in zfs_vnops.c. However, there are some cases when zfs_zget() behaves slightly different than I need: 1) If zp->z_unlinked != 0 then zfs_zget() returns ENOENT. I need it to return

Hi, I am trying to trace some functions that are executed at detach time, and it seems that just having dtrace around to instrument the module is causing a short circuit, whereas modunload will return (device busy). I understand that this makes sense, but how can I get around this if I want to trace stuff at detach time? Thanks, --S

Hi, is it somehow possible to use Dtrace for error injection in a kernel module? Something like changing: - function return value - value of a register If not, can it be implemented? I can do that via kmdb, but I need Dtrace for the time synchronization - chill() action. I can not combine Dtrace & kmdb: dtrace: failed to initialize dtrace: DTrace cannot be used when kernel debugger

Hi All, I have what I think is a ZFS related bug. Unfortunately my simplest test case is a bit cumbersome and I haven't definitively proven that the problem is ZFS related. I'm hoping for some feedback on how to move forward. Quick background: I rip my CD's using grip and produce flac files. I tag the music using Musicbrainz' Picard and transcode it to mp3's within Picard

I'm using Dovceot/IMAP on Linux and Outlook clients on WIN7 workstations. Mail on Linux is stored in Maildir format. I'm searching for where Outook keeps its information on color categories in IMAP. According to Diane Poremsky at slipstick.com, "Outlook stores it in the mapi properties of each message. If you use MFCMAPI to viuw the messages, you'll see the properties."

I've run across a situation where I have a directory of .gz files. I do want to rsync this directory. I've tried without the --compress (because they are already compressed) but the files never get rsynced. Interactively, I get the following error: :rsync error: some files could not be transferred (code 23) at main.c(1045) In the /etc/rsyncd.log, for each of the files, I get:

Hi all Opensolaris works perfectly, but I am not able to boot the xvm kernel on this hardware. I added the -k option in grub, but the system hangs before the hostname line without any debug info. I''ve tried snv from b94 to b99, with the same results. If I install Debian with xen kernel I am able to use pvm and hvm guests. What can I do ? thanks Giacomo -- This message posted from
