similar to: ext4 bug & zfs handling of the very same situation

Hi all, Recently there''s been discussion [1] in the Linux community about how filesystems should deal with rename(2), particularly in the case of a crash. ext4 was found to truncate files after a crash, that had been written with open("foo.tmp"), write(), close() and then rename("foo.tmp", "foo"). This is because ext4 uses delayed allocation and may not

It wouldn''t be proper to start my first post here without congratulations and thanks to the ZFS team for such an impressive piece of work. Anyway, on to my query. I''ve been trying out ZFS, with a particular focus in reducing latency in a specific application. This application has a fair amount of random writing going on in the background (which, of course, ZFS will make

Hi all, What is the current preferred method for backing up ZFS data pools, preferably using free ($0.00) software, and assuming that access to individual files (a la ufsbackup/ufsrestore) is required?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, i have two systems, A (Solaris 10 update 5) and B (Solaris 10 update 6). i''m using ''zfs send -i'' to replicate changes on A to B. however, the ''zfs recv'' on B is running extremely slowly. if i run the zfs send on A and redirect output to a file, it sends at 2MB/sec. but when i use ''zfs send

Is it possible to emulate a unionfs with zfs and zones somehow? My zones are sparse zones and I want to make part of /usr writable within a zone. (/usr/perl5/mumble to be exact) I can''t just mount a writable directory on top of /usr/perl5 because then it hides all the stuff in the global zone. I could repopulate it in the local zone but ugh that is unattractive. I''m hoping

Copying a CD with k3b is no problem, except I want to include on my copy the cbbd data (from freedb.org). I've configured k3b's cddb section according to instructions at <http://www.freedb.org/en/faq.3.html#15> and read every article google could find about "k3b cddb freedb.org config", but still k3b can't manage it. Grip handles getting the cddb data just fine.

Why does ZFS report such small directory sizes? For example, take a maildir directory with ten entries: total 2385 drwx------ 8 17121 vmail 10 Jun 8 23:50 . drwx--x--x 14 root root 14 May 12 2006 .. drwx------ 5 17121 vmail 5 May 25 18:16 .Trash drwx------ 5 17121 staff 6 Jun 9 00:01 .testing -rw------- 1 17121 staff 0 Jun

Here''s some exciting news! Chris Emura, the Filesystem Development Manager within Apple''s CoreOS organization is interested in porting ZFS to OS X. For more information, please e-mail him directly at cemura at apple.com. Speaking for the zfs team (at Sun), this is great news and we fully support the effort. my powerbook hungers for ZFS, eric This message posted from

When I use copy/paste text into a window running vi, if there is a single line starting with '#', in the pasted content, it adds a # to all subsequent lines and indents each an additional level. Is there some way to eliminate this bizarre behavior, preferably globally and permanently so I don't have to repeat some change for every machine/user where I might log in? -- Les

I found something interesting via strace. lda is writing a timestamp with utime before doign the fsync, but I'm really not a C guy, so I have no idea why that's going on via procmail and not via commandline. I assume it's related to the choice of pread64 vs read. when called from commandline (working): read(0, "July 14-20, 2013\n10 courses. Bon"..., 4096) = 4096

Hi, I was wondering if there have been any conversations with backup vendors like Veritas or EMC regarding better integration with ZFS. While I understand they can use the "native" mode of reading files from the filesystem, it would be great if there were agents that had options like making a snapshot and storing a "zfs backup" datastream that could be used for zfs restore.

Hey folks, I'm reading up on gtar for tape archiving and it sounds kind of nasty and not something I really want to rely on. It looks like star from the schily tools is preferred. I'm using Centos (and RHEL) 5.7 which seems to have star but not sdd. Which leads me to believe that the Schily tools are maybe a bit "rogue" My basic requirement with what I'm doing is to use

To be precise, Linus tries hard to prevent ABI changes in the system call interfaces exported from the kernel, but the glibc team had defeated

Hello. I''m a nobody. I use Linux. I have a hard-drive. I want the best / sexiest / what ever fs for my hard-drive, as it isn''t one of those flashy flash drives, which I presume don''t need an fs (???). I was THRILLED that the ZFS for Linux thread started. And, I was equally horrified (and sufficiently annoyed that I am starting this new thread) when it degraded in to

Hello, I believe that ZFS and it''s concepts is truly revolutionary to the point that I no longer see any OS as modern if it does not have comparable storage functionality. Therefore I think that file system/disk manager with similar qualities should be written for Linux. Does Sun have plans to dual license ZFS as GPL so it can be ported to native Linux? If not, is it legal to write

I'm trying to recover data from an audio cd. it is a recording of a live session, made on a professional cd recorder, on the fly. apparently, instead of stopping it and fixating the disc, someone turned off the power. oops. I know that wodim will fixate a disk as long as it was otherwise properly terminated (I've done it more than once), but this one it won't fixate. depending on

Something else that you might want to do is count the number of journal commits that are taking place, via a command like this: perf stat -e jbd2:jbd2_start_commit -a sleep 3600 This will count the number of jbd2 commits are executed in 3600 seconds --- i.e., an hour. If you are running some workload which is constantly calling fsync(2), that will be forcing journal commits, and those turn into
