Motivul este unul simplu – nici moartea nu se traieste in Romania ca in alte parti, pentru ca sentimentele nu pot fi traite pe deplin decat atunci cand se termina hartuiala stampilelor, a semnaturilor, a documentelor, a procesului  absurd. Abia dupa ce se finalizeaza acest calvar poti sa te declari multumit ca “ai rezolvat cu bine”, sa tragi aer adanc in piept si sa reflectezi la cele trecute. Daca ar fi sa traiesti durerea pe deplin, mania in fiecare clipa, tipetele pe care ai vrea sa le scoti, daca chiar i-ai da cu ceva in cap fiecaruia din acest periplu, sau macar le-ai striga cum ti-ar veni la gura, ai ajunge ori la puscarie, ori la balamuc. Desigur, reprimarea unor sentimente are si ea un cost naprasnic , imi spune prietena de care vorbeam– in general iritarea, irascibilitatea, tafnosenia care este evidenta si care izbucneste la cea mai mica atingere intre romani, in public.

“Dom’le, in tara asta, de cand te nasti si pana cand mori, e numai spaga si hartogaraie peste tot”. Cetateanul , la vreo 50 de ani, dupa ce ma masoara de la crestet pana in talpa, imi spune, cu o unda de tristete: “Dom’le, daca asta este ceea ce credeti, inseamna ca nu ati inteles nimic despre Romania. “ Credeam ca vrea sa ma contrazica, dar spune altceva: “Cea mai mare spaga si chinuiala in Romania nu se produce pe timpul vietii, este cea dinainte de a te naste si dupa ce mori”.

trim ext4 raid


Understanding Discard (TRIM) support
Discard (also known as TRIM) is enabled by default in this version of the IO Accelerator driver.
Discard addresses a unique issue to solid-state storage. When a user deletes a file, the device does not
recognize that it can reclaim the space. Instead, the device assumes the data is valid.
Discard is a feature on newer filesystem releases. It informs the device of logical sectors that no longer
contain valid user data. This enables the wear-leveling software to reclaim that space (as reserve) to handle
future write operations.
Discard TRIM on Linux
Discard is enabled by default. For Discard to be implemented, the Linux distribution must support this feature,
and Discard must be enabled.
Under Linux, discards are not limited to being created by the filesystem; discard requests can also be
generated directly from userspace applications using the kernel discard ioctl.
CAUTION: A known issue is that ext4 in Kernel.org 2.6.33 or earlier might silently corrupt data
when Discard is enabled.
The issue has been fixed in many kernels provided by distribution vendors. Check with your kernel
provider to ensure that your kernel properly supports Discard. For more information, see the
release notes for this version of the driver.

IMPORTANT: Currently, MD and LVM do not pass discards to underlying devices in Linux.
Therefore, any ioDrive device that is part of an MD or LVM array will not receive discards sent by
the filesystem.
The LVM release included in Red Hat 6.1 supports passing discards for several targets, but not all
(RHEL 6.1documentation
(http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administrati
on_Guide/newmds-ssdtuning.html)). For more information, see your distribution documents.

revelion

"Se incheie anul, deci prostimea trebuie sa faca circ. N-am inteles niciodata de ce trebuie sa-mi vizitez prietenii in miez de noapte, sa nu dorm si mai grav, sa ne maimutarim cu mese festive, sa trebuiasca sa mananc toate jegurile, in toiul noptii, doar pentru ca se sfarseste anul. Stupid.

Si culmea penibilului : la 12 fix, hai sa urlam, sa pocnim artificii, sa ne pupam si sa ciocnim pahare ca retardatii."
