MDM Trouble Report for 2012 Jun 30 Telescope: 1.3m Observer(s): Gaidos (Hawaii) Instrument: R4K Problem(s) Encountered: Sometime in the middle of the night, Prospero stopped writing fits images to the data disk/directory (/lhome/data). However, it continued to increment the file number, i.e. LAST said the last image written was 180, bu t NEXT said the next image would be 254 or something like that. I verified the path was correct and looked for the missing images without success. There were NO errors reported to standard output during the observations other than the one that has always appeared: pr> go *** Exposure Started *** STATUS: IC> WARNING: Instrument electronics not responding I then took a single image. It did not show up but the counter (NEXT) was again incremented! STATUS: Writing to disk PCTREAD=100 STATUS: Finished 1 of 1 exposures. STATUS: STATUS: DONE: Exposures finished. *** Exposure Completed *** I then did a RUNINIT, keeping everything the same and the counter to its current value. I then took an image. That showed up, and then one by one the missing images started showing up on /lhome/data! It took a few minutes for them to appear, except for the last 14. Instead error messages appeared: CB> ERROR: No SIMPLE card in FITS file #60, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #61, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #62, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #63, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #64, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #65, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #66, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #67, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #68, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #69, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #70, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #71, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #72, skipping... pr> CB> ERROR: No SIMPLE card in FITS file #73, skipping... This seems to be a Caliban issue: Looking at the Caliban log I see 180 written and then what happens after 180 was written is: B% IN: PR>CB status OUT: CB>PR STATUS: AUTOLOG=T DISPLAY=F ADDFITS=T ARCHIVE=F NOSWAP=F INTERFACE=Ne twork +AckSwap CB% IN: PR>CB status OUT: CB>PR STATUS: AUTOLOG=T DISPLAY=F ADDFITS=T ARCHIVE=F NOSWAP=F INTERFACE=Ne twork +AckSwap CB% IN: PR>CB status OUT: CB>PR STATUS: AUTOLOG=T DISPLAY=F ADDFITS=T ARCHIVE=F NOSWAP=F INTERFACE=Ne twork +AckSwap CB% IN: PR>CB status OUT: CB>PR STATUS: AUTOLOG=T DISPLAY=F ADDFITS=T ARCHIVE=F NOSWAP=F INTERFACE=Ne twork +AckSwap Then nothing until CB% IN: IC>CB USE MOUNT UNIX:\CB\/lhome/data OUT: CB>IC STATUS: Path=UNIX:\CB\/lhome/data OUT: CB>IC REQ SWAP CB% IN: IC>CB ACK SWAP CB% IN: IC>CB TRANSFER DISK1 1 PR Initiating file transfer iteration #1... Transferred file #1 (/lhome/data/image.0181.fits) at 33286 KB in 8.01 sec (4156 KB/sec) So it seems there was a problem with Caliban? Any chance of recovering the missing 14 images? ------------------------------ Submitted on 2012 Jun 30 [13:51:48]
