There is a confusion about the name of this file system, then I decided to contact the author (Kirk McKusick) who replied: "The name has always been confusing (my bad). The code is broken into two parts, the part that handles naming (UFS where the U stands for Unix), and the part that handles disk layout (FFS where the F stands for Fast). When the two parts are put together they are called UFS/FFS or more commonly just UFS." Dependency: Package: ufsutils (UFS filesystems utilities) *** NOTES *** - These steps were only made...

Hi, I''m preparing a personal TPC-H benchmark. The goal is not to measure or optimize the database performance, but to compare ZFS to UFS in similar configurations. At the moment I''m preparing the tests at home. The test setup is as follows: . Solaris snv_37 . 2 x AMD Opteron 252 . 4 GB RAM . 2 x 80 GB ST380817AS . Oracle 10gR2 (small SGA (320m)) The disks also contain the OS image (mirrored via SVM). On the remaining spac...

Hi Dears, I am having trouble mounting a partition with UFS file system (FreeBSD), I am trying to build with the following commands: mount-r-t-o ufs ufstype = ufs2 / dev/hdb1 / part mount-r-t-o ufs ufstype = 44bsd / dev/hdb1 / part But appears the following error message: mount: wrong fs type, bad option, bad superblock on / dev/hdb1, missing cod...

I had some trouble installing a zone on ZFS with S10u4 (bug in the postgres packages) that went away when I used a ZVOL-backed UFS filesystem for the zonepath. I thought I''d push on with the experiment (in the hope Live Upgrade would be able to upgrade such a zone). It''s a bit unwieldy, but everything worked reasonably well - performance isn''t much worse than straight ZFS (it gets much faster with c...

Hi, I need to mount a UFS (Unix File System) partition from an external device (ie, live cd). I've seen the kernel-2.6.x-x.x.x.xxx.plus.c4 has UFS support and I've several questions about: ?How I know what FS are supported by my kernel? ?Is CentOS LiveCD edition builded with UFS support? ?Is there another way to ge...

From: Raphael S. Carvalho <raphael.scarv at gmail.com> Change since v1: * Fix bug on dentry structure (thank you specification; btw, sarcasm), and consequently a bug on ufs_readdir. * Add readlink support (applied tests for symlinks whose destionation path were stored in blk pointers and the file itself). * Several improvements. Wrote the documentation below. I think it would be good to push the doc to the wiki as soon as the UFS support gets merged. Unix Fast File...

hi all Try to learn how UFS root to ZFS root liveUG work. I download the vbox image of s10u8, it come up as UFS root. add a new disks (16GB) create zpool rpool run lucreate -n zfsroot -p rpool run luactivate zfsroot run lustatus it do show zfsroot will be active in next boot init 6 but it come up with UFS root, lustatus sh...

Is r/w to a UFS partition using 'guestmount' still an impossibility? From everything I've found, it seems to be something that is not possible at the moment. I was just wondering if that has changed or if there are plans to change that? Here is the issue I'm experiencing: ~# guestmount --rw...

...settings, and have scoured the internet for other peoples' experience with it. (I found the performance improvement in compiling has forestalled the need to add an SSD drive. ;-) I believe that increasing the following values by 10 would benefit most FreeBSD users without disadvantage. vfs.ufs.dirhash_maxmem: 2097152 to 20971520 vfs.ufs.dirhash_reclaimage: 5 to 50 or 60 FreeBSD administrators who have adjusted vfs.ufs.dirhash_maxmem for file server use have found 8 megs to be about minimum to satisfy vfs.ufs.dirhash_mem usage, while I have found compiling larger packages such as Firef...

Hi all! First off, if this has been discussed, please point me in that direction. I have searched high and low and really can''t find much info on the subject. We have a large-ish (200gb) UFS file system on a Sun Enterprise 250 that is being shared with samba (lots of files, mostly random IO). OS is Solaris 10u3. Disk set is 7x36gb 10k scsi, 4 internal 3 external. For several reasons we currently need to stay on UFS and can''t switch to ZFS proper. So instead we have opted...

It's already loading modules successfully, and both UFS version 1 and 2 seems to be working correctly.

Hello Gurus, Greetings. I have been assigned some work on the development of a migration tool. The requirement is that it has to migrate the data on a UFS/VxFs filesystem to an ext2 filesystem. What are the technical apects I will have to look into to achieve the same? Is it possible to change the on-disk structure of the UFS/VxFs filesystem to an ext2 filesystem? The question may sound weird but then that is the requirement. Kindly help me. Ki...

Hi - a question for all ye rsync guru's out there... I have a need to migrate some fairly large Oracle datafiles from a UFS filesystem to VxFS (VERITAS), however I am not being allowed nearly enough outage time to perform a standard file copy migration. The datafiles (of which there are about 4 are about 50GB each in size and on separate UFS filesystems. I am considering instigating a local rsync copy between the two f...

This simple patch adds support for the BSD "growfs" command, so you can grow BSD filesystems [in theory -- see below]. It also adds a new optional group called "ufsutils" which indicates if the libguestfs API supports the guestfs_ufs_growfs call, since it's not available on Fedora. (http://libguestfs.org/guestfs.3.html#availability) I tested this on Debian, and although we appear to be invoking the growfs.ufs command correctly, the growfs command co...

There seems to be an inconsistency between release 4.9-RC and 5.1 ufs support. If I fsck the same ufs (type 1 of course) file system on both releases, each claims that the other has left incorrect summary data in the superblock. Presumably only one can be correct. I just don't know which to blame. I couldn't find a FreeBSD problem report about bad summary...

...ght now I am using Robocopy and I was hoping I could do this with rsync instead. Here is what the freebsd tester box looks like. You can notice the two smbfs mounts. These are some of the engineering windows 2000 machines that I would like to mirror to this freebsd box. /dev/ad0s1a on / (ufs, NFS exported, local) /dev/ad0s1f on /tmp (ufs, local, noatime, soft-updates) /dev/ad0s1g on /usr (ufs, local, noatime, soft-updates) /dev/ad0s1e on /var (ufs, local, noatime, soft-updates) /dev/ad1s1e on /depot (ufs, NFS exported, local, noatime, soft-updates) /dev/ad2s1e on /general (ufs, NFS exp...
