Deploying libvirt with live migration
I have two physical servers: Virt1 and Virt2. I'm setting up live
migration with CentOS 5.5 between the two. I've done this by NFS
mounting /etc/libvirt and /var/lib/libvirt/images on both servers. This
is working well for me except for one thing.
I see the same list of VMs on each server (as expected), but each server
(Virt1 and Virt2) are able to start the same VM at the same time.

Samba mounts failing to Win2003 Server
We have a Windows 2003 fileserver here on a domain. I've been
mounting it via Linux for a couple years now. Some time in the last
three months it stopped working. Perhaps some patch was applied that
broke things? I have no idea what's causing it but I always get a
permission denied error message.

"Too many levels of symbolic links" with glusterfs automounting
I set up a 3.3 gluster volume for another sysadmin and he has added it
to his cluster via automount. It seems to work initially but after some
time (days) he is now regularly seeing this warning:
"Too many levels of symbolic links"
$ df: `/share/gl': Too many levels of symbolic links
when he tries to traverse the mounted filesystems.

[PATCH] use reliable nfs mount options per default
Peter,
we found that nfs over udp will corrupt data under very extrem load,
there is no way to fix it due to the way how UDP works.
TCP will not have these problems.
I also wonder why the package size is only 1k. Everyone who wishes a
slow connection can pass the desired options via the kernel cmdline.
Everyone else prefers probably the fast mount.
The defaults should look more like that:

NFSroot is acting strange in CentOS5
Hello all,
I have observed a problem with a diskless PXE client I am attempting
to configure. PXE/NFS/DHCP/TFTPd server is running CentOS5.1 and the
Diskless workstation's root and kernel was extracted from a CentOS5.1
(custom kernel due to setting to enable Root File System support).
Problem: When the diskless client boots and logs in I notice that my
root user is being squashed, even if I

Xen, NFS performance, rsize, wsize and MTU
We have a Xen 3.0 / Linux kernel 2.6.15 machine with the domU''s
configured for shared /home directories. One of the domU''s is an NFS
server, exporting /home, and the other domU''s all mount this.
It all functions fine, but it''s pretty slow.
I tried untarring a recent Linux kernel tarball. On the NFS server
domU this takes about 25 seconds. I didn''t

specifying mount options in /etc/auto.master
I have this NFS client that used to be on Red Hat 7.3. For mounting user home
directories I used this line in /etc/auto.master file:
/home yp:auto.home rw,rsize=8192,wsize=8192
Moved the box to CentOS 4... The format of the file changed, so I attempted
something like this:
/home -rw,rsize=8192,wsize=8192 yp:auto.home
No habla. Doesn't work. The rsize and wsize options seems to be

CentOS7 and NFS
Hi Barbara,
Thanks for all these suggestions. Yes, jumbo frames are activated and I
have only two 10Gb ethernet switch between the server and the client,
connected with a monomode fiber.
I saw yesterday that the client showing the problem had not the right
MTU (1500 instead of 9000). I don't know why. I changed the MTU to 9000
yesterday and I'm looking at the logs now to see if the

btrfs over nfs
I have been experimenting exporting btrfs subvolumes over nfs. Main
subvolume is filesys1 mounted at /filesys1. Below this is subvolume
base, user1 is in base and documents is in user1. documents is
mounted at /documents. /etc/exports is:
/filesys1/base/user1 172.16.0.0/24(rw,no_acl,no_root_squash,fsid=0)

nfsmount default timeo=7 causes timeouts on 100 Mbps
I think I got it.
Both nfsmount and `mount -t nfs` now default to rsize/wsize = 1 MB.
By lowering this to 32K, all issues are gone, even with the default
timeo=7. And nfsroot=xxx client responsiveness is a whole lot better.
I think when nfsmount was initially written, the default rsize/wsize
were much lower, which matched the timeo=7.
Now they cause the lags/timeouts that I reported.

huge increase in storage activity afther dovecot upgrade
Yes, multiple imap servers using one shared nfs storage. With the same
config on 2.2.13 the public interface traffic was similar to the storage
interface, around 100 mbps.
After we switch to 2.2.27 the storage interface traffic jumped 10 times
while the public interface stayed the same. This make us thinking that
something is wrong and each time a user logs in the whole Inbox content

Increase data length for SMB2 write and read requests for Windows 10 clients
Hello,
We are currently running a Linux Samba gateway with a CephFS
kernel-client to allow Windows 10 clients to transfer data to and from
our Ceph storage cluster. We have been using this in production for a
while now quite successfully but we are finding that our Windows clients
are having their rates limited to ~1 Gbps despite having 10 Gbit
interfaces (iperf tests show a 4.18 Gbps
