The File System . Accounts consume disk space as files are created, copied, edited and mail is sent and received. Disk space is a limited resource and various methods are used to manage it. ... If quotas are used on your cluster, use the SHOW QUOTA command to display information about how much space you have used and how much is available to you. ... If free space on the scratch disk falls below 25%, then all files that are more than 4 business days old will be deleted. ...

When you install or upgrade your system, you need to do a fair amount of work on your disks.

... The formation of the disks of disk galaxies remains poorly understood. ... Many disk galaxies have only the thin disk component, with no bulge or significant thick disk. ... Almost all disk galaxies have an exponential radial surface brightness distribution. The reason for this exponential form is not known; nor is it known when the exponential form is established. ...

... I am developing an Informed Prefetching and Caching system as part of the kernel in which it is very important that the memory assigned to hold the data does not get swapped to disk. Without any thought to swapping I used vmalloc() to assign memory to the data structures of the Informed prefetching system. ... I later realized that most probably the pages assigned using vmalloc() were getting swapped to the disk and when I referenced them, they were brought from the disk rather than memory. ...

Abstract -- Abundances of heavy elements decreases with increasing galactocentric distance almost in all disk galaxies. ... To explain this gradient in young objects and in the interstellar gas one has to assume that a typical disk galaxy is an open system, i.e. it expels some synthesized heavy elements into the circumgalactic space and/or accretes intergalactic gas with zero metallicity, with rates of both processes depending on the galactocentric distance. ...

... SS433 is a close binary system, one star is a supergiant, a second one is a black hole. ... Even a black hole cannot accept such an enormous mass flux, a supercritical accretion disk appears, all the excess gas glows up to several tens of thousands degrees and is ejected off the disk with enormous velocities. ... SAO researchers have found an evidence of the supercritical accretion onto a black hole in SS433, which follows from a brightness variability of the SS433 disk. ...
