fixed /opt/local/bin/zfs-replicate on ms1 to write the snapshot number before starting replication, to avoid permanent error "dataset already exists" after failure |

sync-common script doesn't work on nfs-free apaches; language lists etc not being updated. Deployment scripts need to be fixed? |

so far so good; CPU graphs on image scalers and ms1 look clean, and I can purge thumbs on commons ok |
[production] |
| 01:10 |
<brion> |
trying switching image scalers back in for a few, see if they go right back to old pattern or not |
[production] |
| 01:03 |
<brion> |
load on ms1 has fallen hugely; outgoing network is way up. looks like we're serving out http images fine... of course scaling's dead :P |
[production] |

stopping apache on image scaler boxes, see what that does |

Upgraded pybal on lvs3 |
[production] |

<mark> |
Hacked in configurable timeout support for the ProxyFetch monitor of PyBal, set the renderers timeout at 60s |
[production] |
| 17:58 |
<domas> |
scaler stampedes caused scalers to be depooled by pybal, thus directing stampede to other server in round-robin fashion, all blocking and consuming ms1 SJSWS slots. of course, high I/O load contributed to this. |
[production] |
