I'm on a Supermicro server, X9DA7 motherboard, Intel C602 chipset, 2x 2.4GHz Intel Xeon E5-2665 8-core CPU, 96GB RAM, and I'm running CentOS 6.4. I just tried to use yum to upgrade the kernel from 2.6.32-358 to 2.6.32-431.29.2. However, I get a kernel panic on boot. The first kernel panic I got included stuff about acpi, so I tried adding noacpi noapic to the kernel boot parameters, which at least cha...

Ian, I came across the subject line on a 96GB server with over 85 VMs running. Completely frozen and unresponsive, qemu-dm processes hung on event channels. I''m using the XenServer 6.0 dom0 kernel on top of the xen-unstable tip hypervisor. I believe you solved the issue backporting some event channel patches to the 2.6.32 kernel, as...

But it''s early (for me), and I can''t remember the answer here. I''m sizing an Oracle database appliance. I''d like to get one of the F20 96GB flash accellerators to play with, but I can''t imagine I''d be using the whole thing for ZIL. The DB is likely to be a couple TB in size. Couple of questions: (a) since everything is going to be zvols, and I''m going to be doing lots of sync writes to them, I''m...

I am going to try an experiment with e-mail aggregation where I expect to receive over 1 million e-mails a day from public lists. Can anyone shed some light on hard disk space (to retain this e-mail for long periods) and system specs to be able to handle the load? I am looking to buy a low end box, but that can hold lots of RAM and accomodate a fair number of HD's to store the e-mail while

Hello, I had something interesting happen on a RH8 ext3 system I setup.I am at a loss to understand what happened. Info: This system has two IDE disks, partitioned identically, and the largest partition on each (/dev/hda3 and /dev/hdb3, 96GB each) was mirrored in a linux software RAID-1 configuration. It was running fine for many months. Then I updated the kernel and needed to reboot accordingly. (2.4.18-14.8.0smp -> 2.4.18-27.8.0smp) Problem: Upon a reboot, fsck complained that /first1 (/dev/hda3)'s superblock or partition tab...

I have a rather large box (2x8-core Xeon, 96GB RAM) where I have a couple of disk arrays connected on an Areca controller. I just added a new external array, 8 3TB drives in RAID5, and the testing I'm doing right now is on this array, but this seems to be a problem on this machine in general, on all file systems (even, possibly, NFS, bu...

...result of some behaviour in the syncer. This is with FreeBSD 8.2 (with some local modifications and backports, r231160 in particular). The system has an LSI 9261-8i RAID controller (backed by mfi(4)) and the database and WALs are on separate volumes, a RAID 6 and a RAID 1 respectively. It has about 96GB of RAM installed. What's happening is that the syncer tries to fsync a large database file and goes to sleep in getpbuf() with the corresponding vnode lock held and the following stack: #3 0xffffffff805fceb5 in _sleep (ident=0xffffffff80ca8e20, lock=0xffffffff80d6bc20, priority=-2134554464,...

Hello List, Merry Christmas to all !! Basically I''m trying to boot a Windows 2008R2 DC HVM with 90GB static max memory and 32GB static min. The node config is Dell M610 with X5660 and 96GB RAM and its running XCP 1.1 Many times the node crashes while booting HVM. Sometimes I get success. I have attached the HVM boot log of successful start. Many times the node hangs as soon as the BalloonWorkerThread is activated. In attached txt the ballon inflation rate is constant 4090 *XENUTIL:...

I was learning about the different FS exists. I was working on systems that ReiserFS was the star but since there is no longer support from the creator there are other consolidations to be done. I want to ask about couple FS options. EXT4 which is amazing for one node but for more it's another story. I have heard about GFS2 and GlusterFS and read the docs and official materials from RH on

Running an mmap-intensive workload on ZFS on a X4500, Solaris 10 11/06 (update 3). All file IO is mmap(file), read memory segment, unmap, close. Tweaked the arc size down via mdb to 1GB. I used that value because c_min was also 1GB, and I was not sure if c_max could be larger than c_min....Anyway, I set c_max to 1GB. After a workload run....: > arc::print -tad { . . . ffffffffc02e29e8

Hi All, I am trying to determine whether a mail server cluster based on Dovecot will be capable of supporting 500,000+ mailboxes with about 50,000 IMAP and 5000 active POP3 connections. I have looked at the Dovecot clustering suggestions here: http://blog.dovecot.org/2012/02/dovecot-clustering-with-dsync-based.html and some other Dovecot mailing list threads but I am not sure how many

From: Rodrigo Barbosa <rodrigob at suespammers.org> > Btw, don't quote me on this one :) > I'm only 90% sure of the hotswapping capabilities, and less than 50% > sure about the price :) There _are_ systems with hot-swap CPUs, memory and/or, PCI[-X] slots. They are _not_ commodity and pricey, and require OS-level support. In fact, I believe Linux 2.6 has some support for

Here are patches to do offline deduplication for Btrfs. It works well for the cases it''s expected to, I''m looking for feedback on the ioctl interface and such, I''m well aware there are missing features for the userspace app (like being able to set a different blocksize). If this interface is acceptable I will flesh out the userspace app a little more, but I believe the
