Hello Gurus, Greetings. I have been assigned some work on the development of a migration tool. The requirement is that it has to migrate the data on a UFS/VxFs filesystem to an ext2 filesystem. What are the technical apects I will have to look into to achieve the same? Is it possible to change the on-disk structure of the UFS/VxFs filesystem to an ext2 filesystem? The question may

HI, The question is a ZFS performance question in reguards to SAN traffic. We are trying to benchmark ZFS vx VxFS file systems and I get the following performance results. Test Setup: Solaris 10: 11/06 Dual port Qlogic HBA with SFCSM (for ZFS) and DMP (of VxFS) Sun Fire v490 server LSI Raid 3994 on backend ZFS Record Size: 128KB (default) VxFS Block Size: 8KB(default) The only thing

Hi - a question for all ye rsync guru's out there... I have a need to migrate some fairly large Oracle datafiles from a UFS filesystem to VxFS (VERITAS), however I am not being allowed nearly enough outage time to perform a standard file copy migration. The datafiles (of which there are about 4 are about 50GB each in size and on separate UFS filesystems. I am considering instigating a local

Hi, rsync was running against filesystems /disk5 and /disk7 to back them onto remote server (172.16.101.4) using the following script: if [ `ps -ef | grep -v grep | grep ::d5 | /usr/bin/wc -l` -eq 0 ] then rm -f /etc/rsync5.log echo " --- Disk5 --- starts `date`" > /etc/rsync5.log /usr/local/bin/rsync -a --recursive --compress /disk5/ 172.16.101.4::d5 >> /etc/rsync.log echo

Is it possible to use DTrace to display the number of arguments and their types for userland or kernel functions that are not explicitly instrumented or documented by their authors? We''re talking about functions provided by Veritas VxVM/VxFS and the like, and for example, we might want to try tracing I/Os from App => VxFS => VxVM => ssd driver to see where I/Os get aggregated or

Has anyone had any experience with samba on a Solaris 2.6 system using vxfs file system?

Hello experts, We have a large implementation of Symantec Netbackup 6.0 with disk staging. Today, the customer is using VxFS as file system inside Netbackup 6.0 DSSU (disk staging). The customer would like to know if it is best to use ZFS or VxFS as file system inside Netbackup disk staging in order to get the best performance possible. Could you provide some information regarding this

We are looking at the alternatives to VXVM/VXFS. One of the feature which we liked in Veritas, apart from the obvious ones is the ability to call the disks by name and group them in to a disk group. Especially in SAN based environment where the disks may be shared by multiple machines, it is very easy to manage them by disk group names rather than cxtxdx numbers. Does zfs offer such

Hi Folks.. We have started to convert our Veritas clustered systems over to ZFS root to take advantage of the extreme simplification of using Live Upgrade. Moving the data of these systems off VxVM and VxFS is not in scope for reasons to numerous to go into.. One thing my customers noticed immediately was a reduction in "free" memory as reported by ''top''. By way

Hi, sorry if I am brining up old news, but I couldn''t find a good answer searching the previous posts (My mom always says I am bad with finding things :) However I noticed a difference when creating a zfs filesystem compared with a vxfs filesystem in the available size. ie. ZFS zonedata/zfs [b]392G[/b] 120G 272G 31% /zfs VxFS /dev/vx/dsk/zonedg/zonevol

I''m an Oracle DBA, a dtrace noob, and I''m attempting to resolve an Oracle write performance problem on Solaris 10, Oracle 9iR2. The Oracle DBWR processes have poor write throughput writing to VxFS files. I suspect that the problem may be with POSIX readers/writer file locking. Ideally I''d like to identify, for a given DBWR process, readers/writer file lock contention

How much memory is installed? I''m able to hang an Ultra 60 with 256 MByte of main memory, simply by writing big files to a ZFS filesystem. The problem happens with both Solaris 10 6/2006 and Solaris

Hi, I am using CIFS 2.01.01 on HPUX11V2. CIFS is running in ADS security-mode. Winbind is used to map the userers from the W2K3-Domain (german) to an tdb-file. The user mapping works fine, but I have problems with the ACLS: setting the ACLS to a file or folder from windows leads in "access denied". I'm the owner of the object and have full access. The really crazy thing is,

Hi all! I need a non-root user to be able to perform zfs snapshots and rollbacks. Does anybody know what privileges that should be specified in /etc/user_attr ? Best regards, Lars-Erik Bj?rk

Greetings useRs, Can anyone provide an example how to use ff to feed a very large data frame to glm? The data.frame cannot be loaded in R using conventional read.csv as it is too big. glm(...,data=ff.file) ?? Thank you Stephen B

Hello, was use several cad applications and with one of those we have problems using zfs. OS and hardware is SunOS 5.10 Generic_118855-36, Fire X4200, the cad application is catia v4. There are several configuration and data files stored on the server and shared via nfs to solaris and aix clients. The application is crashing on the aix client except the server is sharing those files from a ufs

I got Large files working fine on Solaris, just make a 64bit binary :). Seriously, I would try making a 64bit binary for HPUX as well(something like +DA2.0W for 64bit PA_RISC).

Hi. I''m managing a HDS storage system which is slightly larger than 100 TB and we have used approx. 3/4. We use vxfs. The storage system is attached to a solaris 9 on sparc via a fiberswitch. The storage is shared via nfs to our webservers. If I was to replace vxfs with zfs I could utilize raidz(2) instead of the built-in hardware raid-controller. Are there any jbod-only storage
