When I try to extract 7z/zip files containing installers (exe) sized about 300M (the problem is almost in this range but most smaller+larger files still work properly!) by 7-Zip context menu or by drag & drop with a active anti-virus scanner, the remaining time in 7-Zip is continuously raising and all other hard disk access is suspended (progress bar freezes), which makes the system freeze when trying to access anything on a hard drive.
When I pack "BenchLink_Waveform_Builder-33503A_V3.20.00.exe" to a .zip and I try to extract it (when AVG is active) again, only 7-Zip file manager button extract works. Shell extension and drag&drop freeze the system about 48...64MB written to disk (this is what I can see after the hard reset). The old Winzip 9.0 SR-1 extracts by all suported ways without problems.
The disk isn't full, but the disk space allowed for this user is full. You need to check quota(1), perhaps persuade the suspect to clean up their junk, or in an outburst of kindness increase it with edquota(8).
I'm going to second xdiskusage. But I'm going to add in the note that it is actually a du frontend and can read the du output from a file. So you can run du -ax /home > /home-du on your server, scp the file back, and then analyze it graphically. Or pipe it through ssh.
Here is a tiny app that uses deep sampling to find tumors in any disk or directory. It walks the directory tree twice, once to measure it, and the second time to print out the paths to 20 "random" bytes under the directory.
If you want speed, you can enable quotas on the filesystems you want to monitor (you need not set quotas for any user), and use a script that uses the quota command to list the disk space being used by each user. For instance:
Which would show me the 20 biggest offenders. However even though I ran this, it did not show me the real issue, because I had already deleted the file. The catch was that there was a process still running that was referencing the deleted log file... so I had to kill that process first then the disk space showed up as free.
You could just destroy the logs as @jrg suggests - but unless the things writing to the log files (mostly syslogd) are restarted that won't actually regain you any disk space, as the files will continue to exist in a deleted state until the filehandles are closed.
This means that nothing in those directories survives a reboot. As far as I can tell, this setup works just fine. Of course, I lose the ability to look at old logs to diagnose any problems that might occur, but I consider that a fair tradeoff for the reduced disk usage.
A floppy disk or floppy diskette (casually referred to as a floppy or a diskette) is a type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device.
The first floppy disks, invented and made by IBM, had a disk diameter of 8 inches (203.2 mm).[1] Subsequently, the 5-inch and then the 3-inch became a ubiquitous form of data storage and transfer into the first years of the 21st century.[2] 3-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5-inch, 8-inch, and other-size floppy disks are rare to non-existent. Some individuals and organizations continue to use older equipment to read or transfer data from floppy disks.
Floppy disks were so common in late 20th-century culture that many electronic and software programs continue to use save icons that look like floppy disks well into the 21st century, as a form of skeuomorphic design. While floppy disk drives still have some limited uses, especially with legacy industrial computer equipment, they have been superseded by data storage methods with much greater data storage capacity and data transfer speed, such as USB flash drives, memory cards, optical discs, and storage available through local computer networks and cloud storage.
The first commercial floppy disks, developed in the late 1960s, were 8 inches (203.2 mm) in diameter;[1][2] they became commercially available in 1971 as a component of IBM products and both drives and disks were then sold separately starting in 1972 by Memorex and others.[3] These disks and associated drives were produced and improved upon by IBM and other companies such as Memorex, Shugart Associates, and Burroughs Corporation.[4] The term "floppy disk" appeared in print as early as 1970,[5] and although IBM announced its first media as the Type 1 Diskette in 1973, the industry continued to use the terms "floppy disk" or "floppy".
In 1976, Shugart Associates introduced the 5-inch FDD. By 1978, there were more than ten manufacturers producing such FDDs.[6] There were competing floppy disk formats, with hard- and soft-sector versions and encoding schemes such as differential Manchester encoding (DM), modified frequency modulation (MFM), M2FM and group coded recording (GCR). The 5-inch format displaced the 8-inch one for most uses, and the hard-sectored disk format disappeared. The most common capacity of the 5-inch format in DOS-based PCs was 360 KB (368,640 bytes) for the Double-Sided Double-Density (DSDD) format using MFM encoding. In 1984, IBM introduced with its PC/AT the 1.2 MB (1,228,800 bytes) dual-sided 5-inch floppy disk, but it never became very popular. IBM started using the 720 KB double density 3-inch microfloppy disk on its Convertible laptop computer in 1986 and the 1.44 MB high-density version with the IBM Personal System/2 (PS/2) line in 1987. These disk drives could be added to older PC models. In 1988, Y-E Data introduced a drive for 2.88 MB Double-Sided Extended-Density (DSED) diskettes which was used by IBM in its top-of-the-line PS/2 and some RS/6000 models and in the second-generation NeXTcube and NeXTstation; however, this format had limited market success due to lack of standards and movement to 1.44 MB drives.[7]
Throughout the early 1980s, limits of the 5-inch format became clear. Originally designed to be more practical than the 8-inch format, it was becoming considered too large; as the quality of recording media grew, data could be stored in a smaller area.[8] Several solutions were developed, with drives at 2-, 2-, 3-, 3-,[9] 3- and 4-inches (and Sony's 90 mm 94 mm (3.54 in 3.70 in) disk) offered by various companies.[8] They all had several advantages over the old format, including a rigid case with a sliding metal (or later, sometimes plastic) shutter over the head slot, which helped protect the delicate magnetic medium from dust and damage, and a sliding write protection tab, which was far more convenient than the adhesive tabs used with earlier disks. The large market share of the well-established 5-inch format made it difficult for these diverse mutually-incompatible new formats to gain significant market share.[8] A variant on the Sony design, introduced in 1983 by many manufacturers, was then rapidly adopted. By 1988, the 3-inch was outselling the 5-inch.[10]
By the end of the 1980s, 5-inch disks had been superseded by 3-inch disks. During this time, PCs frequently came equipped with drives of both sizes. By the mid-1990s, 5-inch drives had virtually disappeared, as the 3-inch disk became the predominant floppy disk. The advantages of the 3-inch disk were its higher capacity, its smaller physical size, and its rigid case which provided better protection from dirt and other environmental risks.
Floppy disks became commonplace during the 1980s and 1990s in their use with personal computers to distribute software, transfer data, and create backups. Before hard disks became affordable to the general population,[nb 1] floppy disks were often used to store a computer's operating system (OS). Most home computers from that time have an elementary OS and BASIC stored in read-only memory (ROM), with the option of loading a more advanced OS from a floppy disk.
By the early 1990s, the increasing software size meant large packages like Windows or Adobe Photoshop required a dozen disks or more. In 1996, there were an estimated five billion standard floppy disks in use.[11] Then, distribution of larger packages was gradually replaced by CD-ROMs, DVDs, and online distribution.
An attempt to enhance the existing 3-inch designs was the SuperDisk in the late 1990s, using very narrow data tracks and a high precision head guidance mechanism with a capacity of 120 MB[12] and backward-compatibility with standard 3-inch floppies; a format war briefly occurred between SuperDisk and other high-density floppy-disk products, although ultimately recordable CDs/DVDs, solid-state flash storage, and eventually cloud-based online storage would render all these removable disk formats obsolete. External USB-based floppy disk drives are still available, and many modern systems provide firmware support for booting from such drives.
In the mid-1990s, mechanically incompatible higher-density floppy disks were introduced, like the Iomega Zip disk. Adoption was limited by the competition between proprietary formats and the need to buy expensive drives for computers where the disks would be used. In some cases, failure in market penetration was exacerbated by the release of higher-capacity versions of the drive and media being not backward-compatible with the original drives, dividing the users between new and old adopters. Consumers were wary of making costly investments into unproven and rapidly changing technologies, so none of the technologies became the established standard.
Flash-based USB-thumb drives finally were a practical and popular replacement, that supported traditional file systems and all common usage scenarios of floppy disks. As opposed to other solutions, no new drive type or special software was required that impeded adoption, since all that was necessary was an already common USB port.
