kernel: HAMMER: WARNING: Missing inode for dirent
I have these messages on the console. Why is this? Is this related with mirroring? Are they serious??

Are '.lockmirror' and 'do_mirror' scripts? If so Please can I get to see them? thanks --Siju
Re: kernel: HAMMER: WARNING: Missing inode for dirent
:I have these messages on the console. :Why is this? Is this related with mirroring? :Are they serious?? : :Thanks : :Siju Were you accessing a snapshot or the live filesystem at the time of the warning? The snapshots have an occassional issue in that the snapshot can be taken inbetween the creation of an inode and the related directory entry. From the snapshot's point of view the directory entry exists but the inode does not. The simplest solution to this issue to do a few 'sync' commands with sleeps before taking a snapshot. I've been trying to fix it in the HAMMER utility itself but I really need to fix it in the snapshot ioctl code. -- Another possible issue is if you were to prune out a snapshot but continue to try to access it. If you do a hammer prune-everything it wipes the snapshots but doesn't rm the snapshot softlinks (a deficiency in the hammer utility). Finally, accessing the snapshots directory on the slave that was mirrored from the master can create a little confusion. The HAMMER utility does not set up a snapshots directory for the slave because it doesn't really know where to put the directory. The slave is a mirror but pruning operations done on the master are not reflected on the slave. Actually this is a problem. I should probably set the snapshots directory on the slave the same as on the master so when snapshots are pruned from the master they also get pruned on the slave. You might have to set up a snapshots directory for the slave, and you would do so by creating the directory on a live filesystem somewhere other then on the slave (which is read-only because its a slave). Using hammer pfs-update. The snapshots on the slave can be managed independantly of the snapshots on the master. These are all things that the utility does not address well and so can be a bit confusing to the user. -Matt Matthew Dillon :Jul 21 17:06:46 dfly-bkpsrv kernel: HAMMER: WARNING: Missing inode for :dirent "Repository" :Jul 21 17:06:46 dfly-bkpsrv kernel: obj_id = 000100b3b22e :Jul 21 17:06:48 dfly-bkpsrv kernel: HAMMER: WARNING: Missing inode for :dirent "Root" :Jul 21 17:06:48 dfly-bkpsrv kernel: obj_id = 000100c4376a :Jul 21 17:06:49 dfly-bkpsrv kernel: HAMMER: WARNING: Missing inode for :dirent "CVS" :Jul 21 17:06:49 dfly-bkpsrv kernel: obj_id = 00010163e8af :Jul 21 17:06:49 dfly-bkpsrv kernel: HAMMER: WARNING: Missing inode for :dirent "Repository" :...

:After reading the man page for 'lockf' I did not get how to implement :it actually. Are '.lockmirror' and 'do_mirror' scripts? If so Please :can I get to see them? : :thanks : :--Siju lockf gets an exclusive lock on the specified lock file and runs the specified program while holding the lock. So if you run lockf wieth the same lock file 50 times in parallel, the programs you run via that lockf are run sequentially, one at a time, and not in parallel. I use -k because there's no point deleting the lock file, and I use -t 0 to cause lockf to abort (exit) if the lock cannot immediately be acquired, to avoid building up lockf commands from cron if something takes extra long to run (or in the case of a mirror-stream, that the previous mirror-stream is still running). .lockmirror is just the lock file created by lockf. It's empty. It is only used for locking. My little do_mirror script does my batch mirroring operation... my cpdup/rdist/whatever. That is the script that my lockf command runs while holding the lock on the lock file. -Matt Matthew Dillon
Grub boot-loading HAMMER
Hello, I'm trying to use Grub to dual boot into DragonflyBSD running on a HAMMER slice. The install wouldnt let me install boot blocks onto ad0s3 where my HAMMER lives, so I logged in as root from the LiveCD and boot0cfg -B ad0s3'd: I'm not sure if this was necessary or advisable. I'm also not sure if this utility is what the installer would have used to install boot blocks, or whether Dragonfly has a different utility. The installer also didnt change the FS type of the partition: its still listed as FAT16, even though it was formatted over. After these install procedures, I tried using grub to load the slice. I tried chainloader'ing it, as well as specifying a kernel /boot/loader. The first gave me an Error 13: invalid or unsupported execution format" and the second an Error 17: unable to mount partition error. Does anyone have suggestions for getting Grub to dual-boot a HAMMER DragonflyBSD? If this is hopeless, what can I do to place the absolute minimum amount of code on a bootable non-HAMMER area, and the dominant part of DBSD in Hammer? I'll be on IRC. Ping rektide. Or respond here. Thank you for your time.

You'll at least need a /boot UFS partition. Also you'll probably have to modify grub to read DragonFly disklabels (although I have a setup here booting with grub, so I don't know how I managed that :). Oh yes, you'd need a disklabel32, not a disklabel64 to have the slightest chance of making grub work. Or try a /boot in ext2, then also grub should be able to read it :D Alternatively you could try using a chainloader in grub. cheers simon -- <3 the future +++ RENT this banner advert +++ ASCII Ribbon /"\ rock the past +++ space for low CHF NOW!1 +++ Campaign \ / Party Enjoy Relax | http://dragonflybsd.org Against HTML \ Dude 2c 2 the max ! http://golden-apple.biz Mail + News / \
