Hi, Recently, I made a btrfs to use. And I met slowness problem. Trying to diag it. I found this: 1. dd if=/dev/zero of=test count=1024 bs=1MB This is fast, at about 25MB/s, and reasonable iowait. 2. dd if=/dev/zero of=test count=1 bs=1GB This is pretty slow, at about 1.5MB/s, and 90%+ iowait, constantly. May I know why it works like this? Thanks. -- To unsubscribe from this list: send the

Hi. I introduced "is_partially_uptodate" aops for OCFS2. A page can have multiple buffers and even if a page is not uptodate, some buffers can be uptodate on pagesize != blocksize environment. This aops checks that all buffers which correspond to a part of a file that we want to read are uptodate. If so, we do not have to issue actual read IO to HDD even if a page is not uptodate

Regardless of the filesystem (i''ve used reiserfs, xfs, ext3), whenever I mount a fresh DRBD partition I get some nasty kernel messages. This is under Debian Sarge, Xen kernel 2.6.11.12-xen0 (dom0) using DRBD v0.7.11 (pulled from Debian "testing"). This is what I did to create the partition. On both nodes I created a new LVM storage device and started DRBD: # lvcreate

I have the exact same issue on several Sunfire v20z (hardware LSI RAID controler). Under high IO load, the raid controler starts complaining with disk errors : [163442.483878] mptbase: ioc0: LogInfo(0x11070000): F/W: DMA Error [163445.172333] sd 2:0:0:0: [sda] Unhandled error code [163445.172338] sd 2:0:0:0: [sda] Result: hostbyte=DID_SOFT_ERROR driverbyte=DRIVER_OK [163445.172345] sd 2:0:0:0:

Here''s some stuff I got from latencytop, not sure if would be helpful:

We have a 3TB external USB drive that I am trying to attach to some CentOS5 servers. I have tried an older Dell PE1950 and a newer R310 but neither one seems to be able to read the drive. It works no problem on windows servers/workstations and I was able to format with NTFS. I know there are different methods for formatting large disks but this one doesn't even seem to show up as a /dev/

hi Geoffrey, Since you are saying it happens on all types of volumes, lets do the following: 1) Create a dist-repl volume 2) Set the options etc you need. 3) enable gluster volume profile using "gluster volume profile <volname> start" 4) run the work load 5) give output of "gluster volume profile <volname> info" Repeat the steps above on new and old
