similar to: Force a sync after each file copy

Hi Folks, I was wondering if I could ask this question here. Initially when I was thinking up how to do this I was expecting block encryption to stay consistent from one 'encryption run' to the next, but I found out later that most schemes randomize the result by injecting a random block or seed at the beginning and basing all other encrypted data on that. In order to prevent

Hello, Currently Dovecot (and any other application, which cares about e-mail delivery) does at least one fsync per mail delivery. Given that hard disk drives have a very limited IOPS, this effectively limits the maximum mail delivery performance to a very low value, under utilizing the available storage IO capacity. Calculating with an average mail size of 50 kB and an average consumer HDD

In 2.4.20-pre5 an optimisation was made to the ext3 fsync function which can very easily cause file data corruption at unmount time. This was first reported by Nick Piggin on November 29th (one day after 2.4.20 was released, and three months after the bug was merged. Unfortunate timing) This only affects filesystems which were mounted with the `data=journal' option. Or files which are

Hi, i too played with mkdiskimage in order to get more Linux examples. When i applied it to a real 2 GB stick with write speed 4 MB/s i had enough time to add some pacifier code to the big zeroizer loop. (-s does not prevent zeroizing on block device. Probably because truncate() fails.) My pacifier is combined with what Perl advised me when i tried "fsync(OUTPUT);". Of course this

Gluster devs, I found the message below in the archives. glfs-health.sh is not included in the v3.0.3 sources - is there any plan to add this to the "extras" directory? What's its status? Ian == snip == Raghavendra G Mon, 22 Feb 2010 20:20:33 -0800 Hi all, Here is some work related to Health monitoring. glfs-health.sh is a shell script to check the health of glusterfs.

The profile seems to suggest very high latencies on the brick at ovirt1.nwfiber.com:/gluster/brick1/engine ovirt2.* shows decent numbers. Is everything OK with the brick on ovirt1? Are the bricks of engine volume on both these servers identical in terms of their config? -Krutika On Wed, May 30, 2018 at 3:07 PM, Jim Kusznir <jim at palousetech.com> wrote: > Hi: > > Thank you. I

The Windows98 explorer (and possibly other programs) incorrectly set the "sync" bit in write requests to network shares. This causes an enormous slowdown as Samba (quite correctly) does a fsync() on the file after each write.

My application always needs to sync file data after writing. I don't want anything handing around in the kernel buffers. I am wondering what is the best method to accomplish this. 1. Do I use EXT2 and use fdatasync() or fsync()? 2. Do I use EXT2 and mount with the "sync" option? 3. Do I use EXT2 and use the O_DIRECT flag on open()? 4. Do I use EXT3 in full journaled mode,

Hi all again: I'm now subscribed to gluster-users as well, so I should get any replies from that side too. At this point, I am seeing acceptable (although slower than I expect) performance much of the time, with periodic massive spikes in latency (occasionally so bad as to cause ovirt to detect a engine bad health status). Often, if I check the logs just then, I'll see those call traces

Hello, It appears the links for the Debian and Ubuntu systems are no loner available. Can someone confirm and if so update the wiki with correct links? Thanks. -- -James

Adding Ravi to look into the heal issue. As for the fsync hang and subsequent IO errors, it seems a lot like https://bugzilla.redhat.com/show_bug.cgi?id=1497156 and Paolo Bonzini from qemu had pointed out that this would be fixed by the following commit: commit e72c9a2a67a6400c8ef3d01d4c461dbbbfa0e1f0 Author: Paolo Bonzini <pbonzini at redhat.com> Date: Wed Jun 21 16:35:46 2017

I've been back at it, and still am unable to get more than one of my physical nodes to come online in ovirt, nor am I able to get more than the two gluster volumes (storage domains) to show online within ovirt. In Storage -> Volumes, they all show offline (many with one brick down, which is correct: I have one server off) However, in Storage -> domains, they all show down (although

Hello, we have a Gluster FS mounted at some /mnt/... path on a Server. The actual physical device behind this resides on some other Server. Now, the requirement is to write files to this Gluster FS Volume in a durable fashion, i.e. for an officially succeeded write the contents MUST have been actually synced to disk on at least one of the Gluster FS nodes in the replica set. Our questions: 1.

Btrfs had some issues with fsync()''ing directories and fsync()''ing after renames. These three new tests cover the 3 different issues we were seeing.
