similar to: Oops when mounting btrfs partition

I converted an ext4 filesystem with btrfs-convert, mounted it, and wanted to do "lzop -d ...". The result was an immediate Oops (btrfs is on LVM, on dm-crypt, on /dev/sdb which is USB-connected). mini-904.img.lzo dentry_open failed BUG: unable to handle kernel paging request at ffffffcd IP: [<c01b5f36>] fput+0x6/0x30 *pde = 00575067 *pte = 00000000 Oops: 0002 [#1] SMP last sysfs

I''ve been working to try to improve the write-ahead log''s performance, and I found that the bottleneck addresses in the checksum items, especially when we want to make a random write on a large file, e.g a 4G file. Then a idea for this suggested by Chris is to use sub transaction ids and just to log the part of inode that had changed since either the last log commit or the last

Hi, I added a new drive to an existing RAID 0 array. Every attempt to rebalance the array fails: # btrfs filesystem balance /share/bd8 ERROR: error during balancing ''/share/bd8'' - Input/output error # dmesg | tail btrfs: found 1 extents btrfs: relocating block group 10752513540096 flags 1 btrfs: found 5 extents btrfs: found 5 extents btrfs: relocating block group 10751439798272

Hello, I''m using kernel 3.1.0 and I have both / and /home as btrfs. I used suspend to ram quite often and never had a problem, but yesterday I''ve suspended to get into a plane and when I resumed my /home was all about input/output errors. Reboot did not help either. My root (/) did not suffer any problems. Today I''ve upgraded btrfs-progs to latest GIT and tried scrub

After doing something silly (not sure what yet) with a server''s 4-drive btrfs raid1 root, I''ve been booting off a 5th drive (also on btrfs) while poking at the original array. I''ve found that errors triggered by poking around on the mounted-but-broken 4-drive raid (on /mnt) cause the system to gradually lock up. This is a 2.6.37rc8 build without any extra patches;

Our code is not ready to cope with a sectorsize that''s not equal to PAGE_SIZE. It will lead to hanging-on while writing something.

I recently got some checksum errors on my btrfs filesystem that seem "interesting". This is on a F18 kernel (3.6.0-3.fc18.x86_64) with the filesystem on a single INTEL SSDSA2CW16 disk (ssd). Its my workstation, so i do normal development on it, i.e. its not a server. Recently I have been doing some virt work, so I''ve been running qemu a lot. I also for some time had a near full

Hi folks! Been using btrfs for quite a while now, worked great until now. Got power-loss on my machine and now i have the "parent transid verify failed on X wanted X found X" problem. So I can''t get it to mount. My btrfs is spread over sda (2tb), sdc(2tb), sdd(1tb). Is this something that an offline fsck could fix ? If so is the fsck-util being developed ? Is there a way to

We have a Zenoss server in our main office monitoring (among many other things) an Apache server in a remote network, with a Tinc link between the two networks. The monitoring simply involves making an HTTP request to a URL once every 5 minutes and confirming that a response page comes back. Most of the requests to this particular web server succeed (and similar requests to other web servers

Originally an attempt to fix: https://bugzilla.redhat.com/show_bug.cgi?id=1570407 However this isn't a complete fix. The OVA supplied doesn't even conform to VMware's own "specification" (I use the word loosely). The OVF inside the OVA references the disk.vmdk file, but the OVA doesn't contain that disk.vmdk file, only a snapshot called disk.vmdk.000000000. Therefore

Could the problem be that the e100 can do IP receive checksumming on the board, but the eepro driver doesn't enable it. When the board is doing checksum offload, then the csum field isn't set. Please try disabling receive checksumming on the e100 driver modprobe e100 XsumRX=0 If this is the problem, it exists both 2.4 and 2.6. On Wed, 27 Aug 2003 18:24:57 +0200 Hannes Schulz

Hi! I used to have arch linux running on 1 btrfs partition (sda1, incl. /boot). When switching to 3.2.5 recently the system fails to boot: (after udevd) /etc/rc.sysinit: line 15: 117 Bus error mountpoint -q /proc and so on, no idea. It used to boot with 3.2.4, but 1) I obviously had some corruption in the tree, when I tried to delete a certain file I hit e.g. "kernel BUG at

In order to improve the performance of fsync, we use the outstanding ordered extents to avoid looking up the checksum from the csum tree. But we didn''t filter out the ordered extents whose csum is still being calculated, when we got those ordered extents, we had to wait for the csum calculation. It made the performance dropped down suddenly. (On my box, it drop down from 56MB/s to

This series adds an initial implementation for scrub. It works quite straightforward. The usermode issues an ioctl for each device in the fs. For each device, it enumerates the allocated device chunks. For each chunk, the contained extents are enumerated and the data checksums fetched. The extents are read sequentially and the checksums verified. If an error occurs (checksum or EIO), a good copy

Hi Ashish, I have tested with your xml in the first mail, and it works for rx_queue_size(see below). multiqueue need to work with vhost backend driver. And when you set "queues=1" it will ignored. Please check your qemu-kvm-rhev package, should be newer than qemu-kvm-rhev-2.9.0-16.el7_4.2 And the logs? tx_queue_size='512' will not work in the guest with direct type interface,
