...o, Does anyone know where full documentation for virsh can be found? Or if the there are any plans to update the man page? The man page lists far fewer commands than virsh lists from its interactive mode when you type help. I noticed this when I was trying to figure out the difference between pool-destroy, and pool-delete. The help entries in the virsh shell are not very informative: virsh # help pool-destroy NAME pool-destroy - destroy a pool SYNOPSIS pool-destroy <pool> DESCRIPTION Destroy a given pool. OPTIONS <pool> pool name or u...

I looked around but could not find any info on how to expand a libvirt managed LVM storage pool. I do not see any virsh command to do it but I was successful using the vgexpand command to add some more storage once I destroyed the pools and then restarted it. I'd like to verify that this is the proper way to grow the storage in a libvirt LVM storage pool. And this brings up a second...

...I was noodling around with creating a backup script for my home system, and I ran into a problem that I''m having a little trouble diagnosing. Has anyone seen anything like this or have any debug advice? I did a "zfs create -r" to set a snapshot on all of the members of a given pool. Later, for reasons that are probably obscure, I wanted to rename that snapshot. There''s no "zfs rename -r" function, so I tried to write a crude one on my own: zfs list -rHo name -t filesystem pool | while read name; do zfs rename $name at foo $name at bar done The results...

I''ve been writing via tar to a pool some stuff from backup, around 500GB. Its taken quite a while as the tar is being read from NFS. My ZFS partition in this case is a RAIDZ 3-disk job using 3 400GB SATA drives (sil3124 card) Ever once in a while, a "df" stalls and during that time my io''s go flat, as in :...

Thank you, and I apologize for conflating the two passes. My main remaining concern is about what happens when there is a node in a function's DSGraph that points to a pool (or pools, if there are multiple callers) that is not in the DSGraph of that function. For example, on page 3 of the 2005 PLDI paper, the DSGraph given for createnode(), Data is pointing to an unlabeled node in the graph. I would like to know specifically what this node is and what would happ...

...g areas. Most of these changes have been small and relatively low impact although combining the allocation of the file_struct with the strings does impact the memory management of file_struct. Attached is a patch that implements the next step. It alters flist memory management and introduces a MM pool layer that reduces malloc overhead and allows destructors to actually release memory to the OS. The patch adds a couple of new files so use patch -p1 and rerun ./configure after patching. -- ________________________________________________________________ J.W. Schultz Pegasystems Te...

I don't really have a specific question, but, as I've been looking through pool allocation and the DS graphs extensively, I wanted to verify that my understanding of the representations used is correct. Therefore, I'm summarizing my understanding below (which, if it's correct, may hopefully be helpful to others). I would appreciate if someone who understands pool...

Hello, I have some questions about Pool Allocation Is it possible for a program to access and manipulate an (automatically allocated) pool at run time? For example, if a program wants to dump all the allocated pools that is using, is it possible to enumerate all those pools and access them (contents and information about the pool) and...
