ext4-fs error device dm-0 ext4_mb_generate_buddy Glasgow, West Virginia

Fix? My setup is almost identical to yours (2x 2TB drives with a 120GB SSD.) That is how I created my cached drives (on-the-fly from the running OS using the "lazy" create fimbulvetr commented Dec 15, 2011 I have this issue as well.

As far as I can tell, the error never happens with ext4 filesystems other than the root FS where executables are running from. This second partition is mounted as '/' once decrypted. I remounted the flashcache drive with the nobarrier option, but it hasn't seemed to help. You signed in with another tab or window.

Was there a prior kernel version where you were not having this particular problem? On Red Hat Enterprise Linux 6, performing an offline resize after consuming all reserved GDT blocks. On a side note I thought that nobarrier would increase performance: http://www.kernel.org/doc/Documentation/filesystems/ext4.txt "If your disks are battery-backed in one way or another, [which a SSD is basically] disabling barriers may safely yes Free blocks count wrong (11735574, counted=11735652).

But I am getting exactly this error on my crucial M4 SSD. yes > Free blocks count wrong (11735574, counted=11735652). > Fix?

Fix?

So people who just google for "ext4_mb_generate_buddy" can often find old bugs that had similar symptoms. jayenashar commented Feb 11, 2012 I've been having a similar problem lately, on linux 3.2-rc4 and 3.2.

We doesn't seems to have this problem on others nodes runnning: Intel(R) Xeon(R) CPU E5345 @ 2.33GHz Intel(R) Xeon(R) CPU 5160 @ 3.00GHz Intel(R) Xeon(R) CPU E5320 @ 1.86GHz Intel(R) Xeon(R) In the meantime, I'll setup a test server and attempt to replicate the error, then try turning off IO barriers, etc. The errors do not show up again. –malisokan Apr 26 '13 at 12:23 Could you please expand on the mdstat matter? nunyaz info (project1750) wrote on 2016-02-29: #50 I am able to reproduce this bug every single time I suspend and then resume one of my laptops.

Problems caused by storage hardware. Several of them needed fixing by fsck. Before loosing anyone's time on this issue, I'll first make sure the hypervisor's RAM is sane. Mohans, any idea why that might have happened or troubleshooting tips for isolating the problem?

We recommend upgrading to the latest Safari, Google Chrome, or Firefox. Going back to the Kernel release 3.0.0-19 of Ubuntu 11.10 makes the problems going away.

It comes up clean and there is no "lost+found" so I guess it's ok. If this is indeed the fix, I'm confused why it would only affect certain cpus? I do not have this problem on linux 3.1. What advantages does Monero offer that are not provided by other cryptocurrencies?

It would seem that using the exact same OS/kernel/binaries, the error doesn't happen on a fresh filesystem, I guess there must have been something about the filesystem image itself that triggered LouieGosselin (0-ubunbu-d) wrote on 2016-03-21: #54 Good work. yes Inodes that were part of a corrupted orphan linked list found.

Either that or remove the 'rw' from the kernel command line. I'm using an "rsync" copy of an original server exhibiting the problem.
