Dear HPS, As was brought up in the meeting today, we need to clean up our usage of the work disk to make space for new activities. I made an attempt to indicate what is what in the table below, which is an annotated output of “du -s -h -c * | sort -h” on the work disk. As you can see, there are a lot of directories where people are either doing 2019 calibration work or 2016 data analysis work. However, there seem to be also quite a bit of legacy files on the disk. Perhaps Bradley and Tongtong can discuss backing up and cleaning up the mc_production directory (purple). Perhaps Holly and Sebouh can discuss backing up and cleanup the directories marked in red. /work/hallb/hps disk space use (>100MB): 270M phansson 325M mskolnik 414M gkalicy 419M baltzell 1.2G tvm 1.3G holly 3.4G uemura 4.7G mgraham 5.6G lmarsicano 14G jeremym 33G fxgirod 79G mrsolt 84G omoreno 171G sebouh - All files are older than 1 year. 242G byale - Almost all files are older than 1/2 year 310G verylg_tritrig (msolt) - All files are older than 1 year. 329G mccaky - Mostly recent Aprime MC files. 564G lgmc_tuples (hszumila) - MC tuples, all older than 1 year. 647G rafopar - Data 182 GB - MC root files for 2016 data analysis. Recent files. - PhysRun2019 431 GB - looks like mostly hodoscope MC. Recent file. 951G celentan - FEE2019 945 GB - Current calibration output. 984G mc_production (hps) - Some current, some old, some very old, MC output - 23G tweakPass6_ApReconAtneg5mm - 36G BeamTilt - 56G alphaFix - 56G SLAC - 134G zeroBeamWidth - 262G PhysicsRun2016 - 403G MG_alphaFix 1015G data (hps) - 851 GB - 2015 tweakpass6 DST root files. - 158 GB - 2016 old passes (Calibpass4b, pass4fail, pass1_allign) 1.3T tkp6_refit (hszumila) - 1.3 T - tuples from 2018. 2.2T ngraf - Mostly FEE filtered files for 2019 calibration. Perhaps this can move to tape and /cache? 8.7T total Note: How old files are was determined with “find . -ctime -365” to check if there are files that were created after 365 days ago. The “-atime” for access time of files does not work reliably on these disks, you can read a file but this will not update the access time.
