Hammer: Transactional file updates

2008-08-01 Thread Michael Neumann
Hi, So Hammer does not guarantee "transctional consistency" of data in case of a crash, only that of meta-data, right? Is there a method to guarantee the write to be transactional, so that I either have the previous "version" of the file or the version that I wrote? Like this: fd = open(file)

Hammer pfs permissions

Hi, It doesn't seem to be possible to assign permissions (like 1777 for /tmp) to pseudo-filesystems: hammer pfs-master /tmp chmod 1777 /tmp ls -la /tmp # still shows "lrwxr-xr-x" for /tmp Regards, Michael

Hammer pruning and pfs

2008-07-28 Thread Michael Neumann
Hi, it's unclear to me whether pruning works locally to a PFS or not. Say I have a snapshots directory with links to PFS#1, e.g. /pfs1/snapshots snap1 -> /pfs1/@0x snap2 -> /pfs1/@0x and I do a hammer prune /pfs1/snapshots will it just prune the PFS#1 accoring to the softlink
