similar to: cli Checking disk i/o

I just built a CentOS7 system on a Zotac NANO PC. I used a 320GB 2.5" HD I had sitting around and installed with Standard Partitions on XFS. The drive is spinning, nonstop. How can I monitor if there is actually disk i/o to warrant this constant spinning. So noatime for all partitions work with XFS?? I did some browsing and the claim is XFS uses realtime which is better? than noatime?

I would check the NANO to see if its firmware has any settings or updates which cover this. Then

Hi all We are implementing samba-ldap to act as an nt pdc and are seeing performance problems. We have a 1ghz, 3gb Ram, 36gb box that is running samba-2.2.5 and openldap-2.0.23 under redhat 7.3 with kernel 2.4.18-3. Clients are all Win2k SP3. All the ldap requests are to the localhost interface. The box is acting as the PDC for the domain, and also sharing diskspace and printers. When we get

Of course it better NOT be doing its own IOs... I like iostat -x 4

Hey! I have a strange condition in one of the servers that I don't where to start looking. I login to the server via SSH (cant doit any other way) and anything that I type is slow HTTP sessions timeout waiting for screen redraw. So, the server is acting "slow". server is bare metal. no virtual services. no alarms in the disk raid note: server was restarted because of power failure.

Hi ! I have a server (Centos 5) that is using a pair of SAS drives to store the data. (Mail server) They are on an adaptec raid controler with a battery backup and write back cache active. >From time to time, I have sever peak io to those data disks (> 400 to 500 iops, > 70 to 100 megs/sec). With iostat, I find that it's almost a write i/o problem. How can I find to which files

Hi people... Here we use Xen 4 with Debian Lenny... We''re using kernel 2.6.31.13 pvops... As a storage system, we use AoE devices... So, we installed VM''s on AoE partition... The "NAS" server is a Intel based baremetal with SATA hard disc... However, sometime I feeling that VM''s is so slow... Also, all VM has GPLPV drivers installed... So, I am thing about

Hi all, I have exchanged my Dell R610 in favor of a Sun Fire 4170 M2 which has 32 GB RAM installed. I am running Sol11Expr on this host and I use it to primarily serve Netatalk AFP shares. From day one, I have noticed that the amount of free RAM decereased and along with that decrease the overall performance of ZFS decreased as well. Now, since I am still quite a Solaris newbie, I seem to

Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs

Dovecot 2.2.18 on CentOS 6 I have a pair of servers setup with MySQL, Postfix, and Dovecot. Replication is setup and working between the two dovecot instances. The problem I'm running into is that a single mailbox receives a lot of messages, at times the rate is multiple messages per second. Delivery from Postfix to Dovecot is via tcp based LMTP.
