RE: problem with gunzip <No space left on device>

[Biradar, Prabhulingamma \(Prabha\)]

Hi Vitaly,

I am curious to know how the gunzip will check for free space available?

Below is the truss command output run on gunzip,

read(3, "D2B0C3B9 d zF894CBB4BE99".., 32768)    = 32768
write(4, " L A S S = " P a r a g r".., 32768)   = 32768
write(4, " O M C - R A N / 3 1 / h".., 32768)   = 32768
write(4, " D   V A L I G N = " t o".., 32768)   = 32768
write(4, " a p h B o d y " > < E M".., 32768)   = 32768
write(4, " >   & n b s p ; < / T D".., 32768)   = 32768
write(4, " " t o p " >   & n b s p".., 32768)   = 32768
write(4, "   i s   5 E S S   D C S".., 32768)   = 32768
write(4, " P   C L A S S = " C o p".., 32768)   Err#28 ENOSPC
fstat64(2, 0xFFBFE600)                          = 0

write(2, "\n", 1)                               = 1
gunzipwrite(2, " g u n z i p", 6)                       = 6
: write(2, " :  ", 2)                           = 2
tarname.tarwrite(2, : write(2, " :  ", 2)                            = 2
No space left on devicewrite(2, " N o   s p a c e   l e f".., 23)
= 23

write(2, "\n", 1)                               = 1
close(4)                                        = 0
unlink("tarname.tar")        = 0
mmap(0x00000000, 8192, PROT_READ|PROT_WRITE|PROT_EXEC,
MAP_PRIVATE|MAP_ANON, -1, 0) = 0xFF380000
munmap(0xFF380000, 8192)                        = 0
_exit(1)

Thanks,
Prabha
