similar to: a few questions about ext3 journal

Hello, Just a few quick, but not very simple questions...: Do any Linux filesystems (besides XFS) support freezing? (ie. in conjuction with LVM snapshots this can allow a mounted filesystem to be frozen [freezing all processes writing to this filesystem] in a valid state (with possibly dangling unlinked files), the device can be snapshotted via LVM, and the original filesystem unfrozen - the

Dear penguin lovers, =) I'm running Linux (2.6) on a satellite receiver with harddrive. The latter is formated in ext3. So far, everthing works fine. Now here's the small problem: The receiver is in the same room I sleep in and when it records at night time I can hear the journaling going on (heads clicking - even though the HD is set to silent mode via hdparm). This is surely due to the

Hi, is there any way, based on userdb/passwdb attribute, how to postpone an email delivery? The purpose is, I need to freeze an account (Maildir++) for a few minutes and new email must not be delivered. But emails must be delivered when account is unfrozen. I found few things about Postfix filters, but I'm not sure it's a good way. Thank you, Milo

Hello everybody, I've my Gentoo's /usr/portage on a loopback btrfs. Just wanted to sync and got an oops. I've a rsync and a ls process in status D now. The system has been in suspend (tuxonice 3.0-rc3) with mounted btrfs, perhaps that is related?

Are there any good options to configure a filesystem so most activity takes place in the RAM buffer with the flush to physical media allowed to lag very far behind? OpenNMS does some data collection that keeps the disk very busy. I don't want to lose the history completely in a crash like you would with a ramdisk, but it wouldn't be a big problem if only the last 10-30 minutes would

This patch adds freeze_fs()/unfreeze_fs() for ocfs2 so that it supports freeze/thaw.

Greetings All, Without going into the specific reasons why I need to do so, is anyone aware of a method (or tool) of watching real-time, human-readable (or system call print) of ext3 filesystem operations on a mounted, active filesystem? Excuse me if this is a duplicate question but I was unable to find any similar ones in the archives. Thanks in advance! Kevin Strong Criminal Information

Hello, Is it possible to install extlinux into a disk image, without being root ? It seems like extlinux --install absolutely requires the specific block device in which extlinux should be installed to be mounted. This prevents from doing an extlinux installation as non-root, which is annoying for build systems such as Buildroot [1] that build a complete Linux system from source, without being

I have an ext3 filesystem mounted r/w on 1 host and r/o on multiple hosts. Dangerous but cost effective. I recently implemented some protection through a fc switch that restricts some hosts to r/o access to the data luns. So if someone types mount -o rw or something, all is not lost. The issue occurs when it's mounted r/w on 1 host and another host attempts to mount it r/o. The mount

hi there, I suppose, it's not an actual WINE problem, but I hope, you can at least tell me, where to get help. I'm running "Lineage 2" with WINE 1.3.10 on Kubuntu 10.10 with proprietary ATI graphics-driver. after a (seemingly) random period of time, the entire system freezes. the only thing possible is moving the mouse-cursor, which doesn't change it's style anymore,

Hi All, the following patches implement the recursively snapshotting and deleting of a subvolume. To snapshot recursively you must pass the -R switch: # btrfs subvolume create sub1 Create subvolume ''./sub1'' # btrfs subvolume create sub1/sub2 Create subvolume ''sub1/sub2'' # btrfs subvolume snapshot -R sub1 sub1-snap Create a snapshot of

Hi, Over the past few years we've been trying to kill poison somehow. There have been a few proposals, but they've all failed to pass the bar and/or to gather significant support (my own proposals included). We (David, Gil, John, Juneyoung, Sanjoy, Youngju, Yoonseung, and myself) have a new proposal to kill undef instead and replace it with poison + a new 'freeze' instruction. We

Is there any method of forcibly umounting an NFS mounted directory? We have a test environment managed under puppet that is also our DR environment. In a DR scenario we''ll be umounting all NFS shares from out test array and remounting to our DR array. However, as this is a test environment we have users logged on, so when Puppet attempts to unmount the test directories, it fails

Hi John, John McCall wrote: >>> Well, we could say non-nsw add and mul are actually "bitwise" operations, so "mul i32 poison, 2" is guaranteed to have its bottom bit zero (but "mul nsw i32 poison, 2" is poison). Of course, there's a limit to how far we can go in that direction, or we just end up with the old notion of undef. Off the top of my head,

Hello, while playing with new jail features, I recognized that manually umounting doesn't work as I'd expect. After jail has been destroyed, the following mountpoint is active: /dev/gpt/jailname1ROOT on /.jail.jailname1 (ufs, local, read-only) There was var mounted to /.jail.jailname1/var but that sucessfully umounted. 'fstat' also shows no open files in /.jail.jailname1 But

Yesterday, I opened a GitHub Issue<https://github.com/rails/rails/pull/7071> about moving Rails inflections to an initializer. The idea wasn''t received well, understandably, as generating a large initializer with new Rails apps is pretty unappealing. However, the core members seemed open to the discussion of alternatives continuing here. For those of you not in the know,
